Answer:
m<AEC = 105
Step-by-step explanation:
they are vertical angles, so they are the same measure
Answer: Step 2
Step-by-step explanation:
The scale factor is defined as image/preimage, so since the image is circle F and the preimage is circle E, k should be equal to (radius of F)/(radius of E), or 1/2, not 2.
Answer:
99 degrees
Step-by-step explanation:
81+a=180, so
180-81=99
a=99
Answer:
a < 3
n < 3
Step-by-step explanation:
We will solve each inequality one by one.
Solve first inequality :
3a - 4 < 5
add 4 both the side
3a < 9
divide 3 both the side
a < 3
Solve second inequality:

subtract 5 both the side

now multiply by -3 both the side and reverse the inequality sign
n < (-3)*(-1)
n < 3
That's the final answer. I hope it will help you.
