Answer:
33 square units
Step-by-step explanation:
4 triangles - 1/2 * 3 * 4 = 24
base is 3 * 3 = 9
24 + 9 = 33
At first, she had +2y in the upper and -5y in the lower.
She multiplied the upper by 5 . Then she had +10y in the upper.
She should multiply the lower by 2 . Then she'll have -10y
there. She'll be able to add the two equations, and the 'y's will
go away. She'll be left with a single equation with only 'x' in it,
and she can solve that one for the value of 'x'.
It is 270 i believe hope it helps
Answer:
Step-by-step explanation:
a = 180 - 2(19) = 142°
b = 90° Triangle in a circle with one side as a diameter makes right triangle
c = 2(19) = 38°
d = 38°
e = 38°
f = 19° alternate angle
g = 19° equilateral triangle
h = 90 - 19 = 71°
