Hi there!
∠C = 40° and triangle ABC is isosceles, therefore:
∠C = ∠A = 40°
Angles in a triangle sum up to 180°, so:
180 = 40 + 40 + ∠A
180 = 80 + ∠A
100 = ∠A
Thus, arc CB has a measure of 100°.
Answer:
10.5 inches
Step-by-step explanation:
The length of the longest diagonal is across two opposite points of the solid, namely
L = sqrt ( 6^2 + 5^2 + 7^2)
= sqrt (36+25+49)
= sqrt(110)
= 10.5"
4.1 > 4.01 > 4.085 > 4.009
I hope this helps! ;D
