Question

find x value , in triangle XYZ if Y is 2x+7 and Zis 45 so, XY is equals to XZ​

Answer 1

Answer:

x = 19

Step-by-step explanation:

Given-

∠Y = 2x + 7

∠Z = 45°

XY = XZ

To Find - x

Solution-

If two sides of a triangle are equal then it is considered as an isosceles triangle. So ΔXYZ is a isosceles triangle. we know that in a isosceles triangle two base angles are equal.

Here, ∠Y and ∠Z are base angles

So, ∠Y = ∠Z

Therefore,

2x + 7 = 45

2x = 45 - 7

2x = 38

x = 38/2

x = 19
