Answer:
x = - 1
y = - 3
z = -2
Step-by-step explanation:
Please see steps in the image attached here.
Step-by-step explanation:
23. area of rect,r = 11 x 3.5 = 38.5cmsq
area of tri, t = 6 x3.5/2 = 10.5 cmsq
area of shaded region, sr = r-t
=> sr = 38.5- 10.5 = 28.5cmsq
24. area of square, s = 10x10 = 100mmsq
area of circle, c = pi x 5^2 = 78.5mmsq
area of shaded region, sr = s - c
=> sr = 100- 78.5 = 22.5mmsq
25. area of circle, c = pi x 6^2 = 113.04insq
area of tri, t = 6x12/2 = 36insq
area of shaded region, sr = c - t
=> sr = 113.04 - 36 = 77.04insq
Answer: Y= 86 X=94
What I did is, the angle minus 86 to give me 94
Step-by-step explanation:
15 = |x| - 5
|x| - 5 = 15
|x| = 15 + 5
|x| = 20
x = ±20
x = -20 or 20
Option → B
Write the equation: x + 42 + 30 = 131
Combine like terms: x + 72 = 131
Subtract 72 from both sides: x = 59
