Number 1 is 1/20 ,so number 0.5 is 1/40 of 20. so p=100/40 = 10/4 = 2.5%
so 0.5 is 2.5% of 20
proof: 2.5*20/100 =50/100 = 0.5
Your answer would be 0.875.
Answer:
95 degrees
Step-by-step explanation:
since angles 1 and 4 are vertical angles, they are congruent
3x+10=4x-15
3x-4x=-15-10
-x=-25
x=25
x=25 degrees
angles 4 and 7 are supplementary due to them being alternate exterior angles
lets find the measure of angle 4:
4x-15
4*25-15
100-15
85 degrees
Now, lets find the angle measure of angle 7:
85+x=180
x=180-85
x=95
So, the angle measure of angle 7 is 95 degrees
Answer:
x = 38
Step-by-step explanation:
it is a 90 degree angle, so x + 52 = 90
x = 90 - 52
x = 38
