From the figure, we can conclude that the little triangle is an isosceles triangle, the greatest angle is 90 because ∠A = 90 and they are supplementary, therefore, using the triangle sum theorem:
Step-by-step explanation:
0.4 x + 3.9 = 5.7
hope 0.4 x = 5.78 - 3.9
0.4x = 1.88
x = 1.88/0.4
x = 4.7
C and d
when x = 2 , f(x) = x^2 = 4
and
when x = 1 f(x) = 5
Answer: 4.55
Step-by-step explanation:
6.50x2 = 13 + 9.75 = 20% = 4.55
hoped this helped lol
