What expression represents the measure of angle x?

1 answer:

5 0

An isosceles triangle is a triangle that has 2 equal sides and 2 equal angles.

side XY = side XZ
∠Y = ∠Z
Since ∠Y = a° then ∠Z = a°

Because interior angles of a triangle sum up to 180°, we simply need to find the difference between 180° and the 2 known angles to solve for the measure of angle X.

∠X = 180° - 2a°

if 1 mile is 5280 feet, and it is 2 miles from Ellie's house to the school, about how many feet is it from ellie's house to the

Bess [88]

This is a conversion problem. We know that 1 mile is 5280 feet, right? Since Ellie lives 2 miles, and two is double of 1, we just take 5280 and multiply that by two (or add it twice) to find how many feet is between Ellie's house and school. 5280 x 2 = 10560 (you get the same answer if you add 5280 twice). Therefore, 10560 feet lies between Ellie's house and school.
