Answer:
The correct answer is option C
They are complementary angles
Step-by-step explanation:
From the figure we can see two angles <ABC and <LMN,
<u>To find the correct option</u>
From figure we get,
m<ABC = 20°° and m<LMN = 70°
m<ABC + m<LMN = 20 + 70 = 90°
Therefore <ABC and <LMN are complementary angles
The correct answer is option C
They are complementary angles

Answer:
A. (125.6 in)
Step-by-step explanation:
R = d / 2 = 40 / 2 = 20 in
Circumference is:
S = 2*π*R=2*3.14*20=125.6 in
Answer:
77.14 minutes.
Step-by-step explanation:
Jack's time = 3 hours
Jill's time = 2.25 hours = 2 1/4 = 9/4 hours
Combined time = x
Rates :
Jack = 1/3 ; jill = 1 / 2.25 = 1 / 9/4 = 4 /9
Combined rate = 1/x
Setting up the equation :
1/3 + 4/9 = 1/x
Lcm of 3 and 9 = 9
(3 + 4) / 9 = 1/x
7/9 = 1/x
Cross multiply :
7x = 9
x = 9/7 hours
x = (9/7)* 60
x = 77.14 minutes
Combined time = 77.14 minutes.
Answer: 6
Step-by-step explanation: -8 x -8 = 64
64 - -58 = 6
