Question

how to find the value of X with clear explanation pls?

Answer 1

Hy there,
This is an isosceles traingle as the two sides are equal. Also, the two angles are equal.
Angle Y= Angle Z
Implies 2x+7=45
Implies 2x=45-7
Implies 2x=38
Implies x=38/2=19
Implies x=19
AngleY= 45degree
Hope it helps.
Thanks

Answer 2

hello ,

this is an isocles triangle in which two sides n two angles are equal.

here, base angles are equal
angle y = angle z.

so ,

2x+7= 45

2x= 45-7

2x = 38

X = 38/2

X = 19.

so , 2x +7 = 45

2(19)+7 = 38+7 = 45

so angle y = 45°

so , angle y = 45 , angle z = 45 then angle X= ?

add angle y and angle z and then subtract it from 180°

45 +45 = 90 °

we know that sum of angles must be 180

180 - 90 = 90°

angle X = 90°

angle y = 45°

angle z = 45°

hope it helps you..
