use the percent error formula.

in this problem,
e= 75
t=90
substitute and solve.

16%
we are dealing with percents so rounding to nearest whole number will suffice.
hope this helps!
Answer: y = 7
Step-by-step explanation:
√8y - 7 = 7
(√8y - 7)^2 = (7)^2
8y - 7 = 49
+7. +7
8y = 56
Y = 7

Answer:
Correct answer is x = 28°
Step-by-step explanation:
Okay we know Angle A is 2x + 2
Angle B is 90
Angle C is 180 - 148 = 32 ( straight line angle is 180)
Sum of all angles should be 180 in a triangle
which means
A + B + C = 180
2x + 2 + 32 +90 = 180
2x + 124 = 180
2x = 180-124
2x = 56
x = 56/2
x = 28
