The complement is equal to 90 so the complement to 70 is 20. the supplement adds to 180 so the supplement to 70 is 110. if you are talking about x... it’s an isosceles triangle so the base angles are the same and the angles in a triangle add to 180 so 180-(70+70)=40 so x=40 so the complements is 50 and the supplement is 150
Since we know that they have to e similar, it is a 20ft tall flagpole. the shadow of the girl is half of her height, so since the flag pole shadow is 10ft it is simple 10 multiplied by 2
Your answer is 0.110 L
110mL=0.110L
∠3 and ∠4 are angles that must be supplementary.
Ok so the triangle part is 10 but I don’t know what the rectangle part is but the formula for a rectangle is A=base x high
