find the missing information

x = m angle a =

x = 21.25

Angle A = 68.75

Step-by-step explanation:

This is an isosceles triangle because two sides are congruent. So angle A is equal to angle C

(3x + 5) + (3x + 5) + 2x = 180

3x + 5 + 3x + 5 + 2x = 180

3x + 3x + 2x + 5 + 5 = 180

8x + 10 = 180

8x = 180 - 10

8x = 170

x = 170 ÷ 8

x = 21.25

Angle A = 3x + 5

3x + 5

3(21.25) + 5

63.75 + 5

= 68.75

Check.

68.75 + 68.75 + 2(21.25) = 180

137.5 + 2(21.25) = 180

137.5 + 42.5 = 180

180 = 180

(Correct)

the answer will be the last one

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
