(b+1) (b+10) hopefully this is right
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:
Step-by-step explanation:
hello,
pls find below the graph
we need to find the point of intersection between both lines
which is (4,3)
hope this helps
Since that angle is 45 degrees, the white triangle is an isosceles triangle. Therefore, the hight of the big triangle is equal to 12. The are of the shaded triangle is 4x12/2 = 24
B) 7/10
It is B because there are 7 out of 10 possibilities that you would get a number greater than 7 or an odd number.
