Acarpenter designs an a-frame chalkboard. its support bars form the legs of an isosceles triangle.

angle for triangle is 180°

angle ACB is 75° because it has mention that is an isosceles triangle

So that angle of BAC is 180°-75°-75°=30°

it has the same slope and a different y-intercept

hope this : )

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

happy to

pls mark as brainliest
