Answer:

Answer z = 55

Step-by-step explanation:

Remark

I think you have to assume that the horizontal line is a straight line. If that is so, the other line, the one that looks like it is going up and to the left, cuts that horizontal line in such a way that the angles are supplementary. Supplementary angles are angles that add up to 180 degrees.

Equation

2z - 10 + 80 = 180 Combine the like terms on the left.

Solution

2z + 70 = 180 Subtract 70 from both sides.

2z + 70 - 70 = 180 - 70 Combine

2z = 110 Divide by 2

2z/2 = 110/2 Do the division

z = 55 Answer

Answer:

z=55

Step-by-step explanation:

The two angles form a straight line which is 180 degrees

80 + 2z-10 = 180

Combine line terms

70 +2z = 180

Subtract 70 from each side

70-70 +2z= 180 -70

2z = 110

Divide by 2

2z/2 = 110/2

z = 55

A triangle has angle measurements of 61°, 84°, and 35°. is this triangle isosceles?

Answer: No

Step-by-step explanation:

This is not an isosceles triangle because there are different angle measurements. The rule of an isosceles triangle is that it must always have two equal sides and angles.

If _____, use threshold braking any time you need to brake hard.

Inessa [10]

Answer:

The correct option is;

A. You don't have ABS

Step-by-step explanation:

A car braking system works by the friction action the break pad applies on the wheels, when the break is applied with much force, due to hard and sudden breaking of the motion of the vehicle, the break pad stops the rotation of the wheels but the vehicle could however continue skidding due to the high initial momentum

The being skidding vehicle in a situation of kidding increases the likelihood for an accident as the the vehicle can no longer be controlled at the steering either

Threshold braking is the technique of bringing the vehicle to a stop or slowing down in the shortest time possible by applying an optimum breaking force during breaking

Anti-lock Braking System is a safety feature that prevents skidding by keeping the wheels of the vehicle or aircraft from locking when excessive break is applied such that traction maintained between the wheels and the road.

Stephen & Richard share a lottery win of £2950 in the ratio 2 : 3. Stephen then shares his part between himself, his wife &a

horsena [70]

Answer:

Stephen's wife got £354 more than his son.

Step-by-step explanation:

Given:

Amount of Lottery = £2950

Now Given:

Stephen & Richard share a lottery amount in the ratio 2 : 3

Let the common factor between them be 'x'.

So we can say that;

$2x+3x=2950\\\\5x = 2950$

Dividing both side by 5 we get;

$\frac{5x}{5}=\frac{2950}{5}\\\\x = 590$

So we can say that;

Stephen share would be = $2x =2\times 590 = \£1180$

Now Given:

Stephen then shares his part between himself, his wife & their son in the ratio 3 : 5 : 2.

Let the common factor between them be 'y'.

So we can say that;

$3y+5y+2y=1180\\\\10y=1180$

Dividing both side by 10 we get;

$\frac{10y}{10}=\frac{1180}{10}\\\\y=118$

So Stephen's wife share = $5y = 5\times 118= \£590$

And Stephen's son share = $2y=2\times118 =\£236$

Now we need to find how much more her wife got then her son.

To find how much more her wife got than her son we will subtract Stephen's son share from Stephen's wife share.

framing in equation form we get;

Amount more her wife got than her son = $590-236 = \£354$

Hence Stephen's wife got £354 more than his son.

for a class gardening project 1/3 of mrs gordon's students planted marigolds and 1/2 planted tulips what fraction of the class p

vladimir2022 [97]

Get them to have a common denominator so you can add them
(1/3)×2= 2/6 and (1/2)×3= 3/6
Add them together
(2/6)+ (3/6)= 5/6
So 5/6 of the class planted either marigolds or tulips and 1/6 of the class planted neither
