H(x)=-5(x 1/2)^2+5/4 Or X1=0,x2=1
Answer:
17 units
Step-by-step explanation:
s = √15² + 8² = √289 = 17
The answer's D. 35/22
Well i have to write 20 words so dont mind this part
When added, these two angles are supplementary, meaning that their sum is 180. This means that we can do the following to find x, and eventually DBC:
3x+67+4x+50=180
Simplifies to:
7x+117=180
Then by the Subtraction Prop. of Equality:
7x=63
Then divide by 7 on both sides to get that x=9.
We then substitute 9 into angle DBC.
4(9)+50
=36+50
DBC=86
