Answers: Angle A is 36 degrees, angle C is 54 degrees
=================================================================
Work Shown:
The angles A and C are complementary, meaning they add to 90 degrees.
(Angle A) + (Angle C) = 90
(2x-4) + (2x+14) = 90
(2x+2x)+(-4+14) = 90
4x+10 = 90
4x+10-10 = 90-10 .... subtract 10 from both sides
4x = 80
4x/4 = 80/4 ..... divide both sides by 4
x = 20
If x = 20, then,
angle A = 2x-4 = 2*20-4 = 40-4 = 36 degrees
angle C = 2x+14 = 2*20+14 = 40+14 = 54 degrees
Note how A+C = 36+54 = 90 which helps confirm our answers.
Answer:
Option ii is right
Step-by-step explanation:
Given that according to the U.S. Department of Education, approximately 57% of students attending colleges in the U.S. are female.
(Two tailed test at 5% significance level)
Test statistic =1.42
Here since proportions we use Z test
p value = 0.156
(ii) P-value =0.156
Answer:
y= 18
x= 15
Step-by-step explanation:
24 ÷ 16 = 1.5
12 x 1.5 = 18
10 x 1.5 = 15
