Answer:

d. m∠Q = 75 degrees

Step-by-step explanation:

The sum of the angles in a triangle is 180°. This triangle is marked to show it is an isosceles triangle, so the two base angles have the same measure.

∠P +∠Q +∠R = 180°

x° +(2x +15)° +(2x +15)° = 180°

5x = 150 . . . . . . . . . . . . . . . . . . . divide by °, subtract 30

x = 30 . . . . . . . . . . . . . . . . divide by 5

m∠Q = (2x +15)° = (2(30) +15)°

m∠Q = 75°

2V2 km 2 km X A) 2V5 km C) 2 km B) 2V3 km D) 4 km HELP PLEASEE

Rasek [7]

Answer:

$x=2\sqrt3\ km$

Step-by-step explanation:

Given that,

The base of a triangle = 2 km

The perpendicular height of the triangle = $2\sqrt{2} \ km$

We need to find the value of x. It is the Hypotenuse of the triangle. It can be solved as :

$x=\sqrt{(2\sqrt{2})^2+2^2 } \\\\=2\sqrt{2+1 } \\\\=2\sqrt3\ km$

So, the value of x is equal to $2\sqrt3\ km$ .

Which of the following is the missing reason? Statements Reasons two thirds times x plus 7 equals negative 5 Given 2x 21 = â’15

pentagon [3]

The correct option is B. Distributive property

Given,

$\frac{2}{3} x+7=-5\\$

On solving the above equation,

multiplying both sides by 3 we, get

$2x+21=-15$

now subtracting 21 from both the sides,

$2x=-36\\$

dividing both the sides by 2 we get,

$x=-18$

Since in the above steps we follow all the giving property except the distributive property.

Hence the correct option is B. Distributive property.

Evaluate the limit. lim x ? 5 (x-5)^2/x-5

slega [8]

As x approaches 5
hmm, we can divide the (x-5) from top and bottom to get x-5
if we input 5 for x we get
5-5=0
it approaches 0 as x approaches 5
