The area is 80 just time 10 and 2 and 4
Answer: r=8
Step-by-step explanation:
-400/-8=400/8=5, then 48=6r equals 8.
I believe the answer is 9.
Answer:
3) 16.2
Step-by-step explanation:
The supplement to the 115° angle on the right is 65°, the same as the angle at upper left. The vertical angles at C are the same measure, so this tells you that the two triangles FCB and ACD are similar by the AA similarity postulate. That being the case, corresponding sides are proportional:
CB/CD = CF/CA
CB = CD·CF/CA = 7.2·21.6/9.6
CB = 16.2

When given two "point-to-point" triangles like this, quite often there is some sort of similarity relationship involved. First, you need to figure out what it is; then you need to make use of it as needed to answer the question being asked.
Pretty sure it is D
if you solve for the intercepts you get these answers
y-intercept is 6
x intercept is 2
