Answer:
8 ft
Step-by-step explanation:
The area (A) of a triangle = 
bh
where b is the base and h the perpendicular height
Using b = 20 and h = 12, then
A = 0.5 × 20 × 12 = 120 ft²
Using b = 30 and perpendicular height = h, then
0.5 × 30 × h = 120
15h = 120 ( divide both sides by 15
h = 8
Answer:
Step-by-step explanation:
let 2x be the length of chord tangent to first circle.
so x=√(14²-6²)=√(14+6)(14-6)=√(20×8)=√160=4√10
length of chord=2x=2×4√10=8√10
Answer:
Perpendicular
Step-by-step explanation:
The two equations intersect at a right angle, so they are perpendicular.
4000000+400000+8000+700+30
<span> x=<span><span><span><span>3</span> and </span></span>y</span></span>=<span>2 to check use the first equation y=5x-13 you plug in x which is 3 5 times 3 equals 15 15-13 equals 2 y=2</span>
