Answer:
x = 36.5
Step-by-step explanation:
The two triangles are similar so we can use the similarity ratio to find x
AB ~ DE and BD ~ BA
15/31 = x/(x+39) cross multiply expressions
31x = 15x + 585
31x - 15x = 585
16x = 585 divide both sides by 16
x = 36.5 approximately
It’s 3 less then measure of its complement 6°
Answer:
The midpoint is (4,3)
Step-by-step explanation:
I attached the midpoint formula.
<u>( -1 + 9 )</u> <u>( 4 + 2 )</u>
2 2
8 / 2 = 4 6 / 2 = 3
(4,3)
Answer:
Part A: f(4) = 2
Part B: k = -7
Step-by-step explanation:
f(4) simply means what the y-value of the graph is when x = 4.
The parabola crosses the coordinate (4,2). In other words, when x = 4, the graph equals 2.
Part B asks to solve the equation: f(4) + k = -5
We already know from Part A that f(4) = 2. So simply substitute 2 for f(4):
2 + k = - 5
Substract 2 from both sides:
k = -7
Answer:
x = 2
z = 89
Step-by-step explanation:
13x + 65 = 91
subtract 65
13x = 26
divide by 13
x = 2
91 + z = 180
subtract 91
z = 89
