Question

can u answer this pls pls​

Answer 1

Answer:

option d:

x=25 ,y=14

Step-by-step explanation:

triangle BAC is congruent to triangle QRP by side -angle-side criteria.

therefore,

we can use

angle A and angle R

as these angles are congruent

angle A = angle R

putting values of angles

2x+15 = 5x - 60

solving this equation

75 = 3x

x = 75/3

x = 25

we found value of x.

Now,

side AB is congruent to side QR

so..

we can say

side AB = side QR

putting values of sides

3x +10 = 5y + 15

putting value of x in this equation

3 *(25) + 10 = 5y + 15

solving given equation to find value of y

75 + 10 = 5y + 15

85 = 5y + 15

5y = 85 - 15

5y = 70

y = 70/5

y = 14

hence,value of y is also found.

so..

x = 25 ,y = 14

option d is correct answer.
