It is an isosceles triangle which means two sides are the same and when two sides are the same then the two angles are the same. The bottom one is 80 degrees so the other angle equals to 80 degrees Add both 80 degrees angle 80+80= 160 In a triangle all the angles equal to 180, so now you subtract 180-160 = 20 The angles are 80, 80 ,20 The 20 is on top and the two 80 are on the bottom
Answer:
20⁰
Step-by-step explanation:
As the two sides are equal , this two angles are 80⁰. Last angle is x
By using angle sum property
x + 80 + 80 = 180
x = 180 - 160
x = 20⁰

Which answer describes the simpler problems that could be used to solve this story problem? Emily paid a total of $109.95 for 4 pairs of sandals and a pair of boots. Each pair of sandals cost the same amount. The pair of boots cost $29.99. How much did 1 pair of sandals cost? A. Subtract the cost of the boots from the total cost. Divide that answer by 4. B. Add the cost of the sandals and the cost of the boots. Divide the sum by 4. C. Multiply the total cost by 4. Subtract the cost of the boots. D. Divide the total cost by 4. Add the cost of the boots.
Answers
Your answer here is.... A.) Subtract the cost of the boots from the total cost. Divide that answer by 4 And since the questions asks "How much did 1 pair of sandals cost?"
We will figure this out! Soo first subtract the cost of the boots from the total cost $109.95 - $29.99 = $79.96
Now divide that answer by 4 $79.96 ÷ 4 = $19.99
So this means that each of our sandals cost $19.99 :)

Find the next three terms.
13,9,5,1...
Answers
it will be -3 then -7 then -11
you go down by 4
Since the list is subtracting/decreasing by 4 every time, the next three terms would be -3, -7, and -11
Which ratios are equal to each other? 1:16 and 2:8 or 2:32 and 4:8 or 1:64 and 4:16 or 1:16 and 4:64
Answers
It would be the one that says " 1:16 and 4:64 " because when you multiply 4 x 16 you would get 64. I hope de I helped you today
