Given:
In triangle
.
To find:
The value of y.
Solution:
In a right angle triangle,

In triangle BGU,



Isolating y, we get



Therefore, the correct option is A.
Answer:
The answer is a _10×+8y=15
Answer:
We let x 1 = 13, y 1 = 8, x 2 = 9, y 2 = 6, x 3 = 4, y 3 = 2, x 4 = 8, y 4 = 4 and the area is given by The absolute value of the cross product of two vectors a →, b → ∈ R 3 spanning the parallelogram is its area:
Step-by-step explanation:
Answer:
x = - 7
Step-by-step explanation:
( x + 139 ) and 132 are vertically opposite angles.
Vertically opposite angles are equal,
x + 139 = 132
x = 132 - 139
x = - 7
