Answer:
Checkpoint B = (-9,5)
Step-by-step explanation:
Here is an image of the graph and coordinates.
Answer:
B.
the complementary angles form a right angle with the shared ray
A = h x b; where A = area of a triangle; h = height of the triangle; b = base of the riangle;
So, we have the equation : 110 = (3b - 8)b;
We solve the equation 3b^2 - 8b - 110 = 0;
The positiv solution is b = 7.53 cm;
h = 3 x 7.53 - 8;
h = 14.59 cm;
The answer is
a) 11/15
b) 1/18
The answer would be 18
Hope that helps.
