FIND THE VALUE OF X.

B

Step-by-step explanation:

Sum of angles in a Right angled triangle is 90°

(x + 5)° + (2x - 2)° = 90°

x + 5° + 2x - 2° = 90°

x + 2x = 90° + 2° - 5°

3x = 92° - 5°

3x = 87°

x = 87°/3

x = 29°

y = i/2 xtnop + (3i/2 tnop+ 1)

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
