Answer:

Since, a triangle’s interior angles makeup 180°

80°+60°+y=180

140°+y=180

y=180°-140°

y=40°

But, it can be option A because it’s an equilateral triangle and the angles don’t math, an equilateral triangle has equal angles

So, it’s one of them

Answer:

Step-by-step explanation:

Sum of angle in a triangle=180°

Given angle are= 60°,60°,y°

So 60+60+Y=180

Y=180-120

Y=60°(option d) is answer

A painter is going to apply a special coating to a triangular metal plate on a new building. Two sides

viva [34]

Answer:

$Area = 90.03cm^2$

Step-by-step explanation:

Given

$s_1 = 14.9$

$s_2 = 14.7$

$\theta = 124$ --- angle in between

Required

The area of the plate

Since $\theta = 124$ is between $s_1$ and $s_2$

The area is:

$Area = \frac{1}{2} * s_1 * s_2 * \sin(\theta)$

$Area = \frac{1}{2} * 14.9 * 14.7 * \sin(124.7)$

$Area = \frac{1}{2} * 14.9 * 14.7 * 0.8221$

$Area = 90.03cm^2$

For the equation 3(7 + x) = 3x + k, which value of k will create an equation with Infinity many solutions a) 7 b) 21 c) 10 d) 3

Svet_ta [14]

Answer:

Step-by-step explanation:

We have to create an identity

3x + 21 = 3x + k

if we substitute k with 21 we have

3x + 21 = 3x + 21

that is an identity so it’s true for every value of x

In a standard deck of cards what is the probability of choosing a red king replacing it and then choosing and then a club.

Vika [28.1K]

Answer:

1/104

Step-by-step explanation:

The probability of choosing a red king is 2/52 since there are only two red kings in a deck of 52 cards...the probability of choosing a club would be 13/52 since there are 13 club cardsin a deck of 52 cards

Therefore the probability of choosing both by replacing the king would be 2/52 × 13/52 giving us 1/104

The slope of every horizontal line is 0 because that is based on the formula. If it's horizontal on the x axis for example, the point slope will be 0,0, also the horizontal line is the numerator, i think. And the undefined slope is vertical because it's the denominator.
