is the ratio of the length of the leg opposite angle B to the length of the hypotenuse:
It will be the same as , which is the ratio of the length of the leg adjacent to angle A to the lenght of the hypotenuse.
Answer:
40.3 in²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h (a + b)
where h is the height and a, b the parallel bases
Here h = 6.2, a = 8, b = 5, thus
A = × 6.2 × (8 + 5) = 3.1 × 13 = 40.3 in²
17. First expand the left side:-
(2x + 1)(ax + b)
= 2ax^2 + ax + 2bx + b
= 2a x^2 + x(a + 2b) + b = 6x^2 - 5x + c.
Comparing coefficients:-
2a = 6 so a = 3
a + 2b = -5
3 + 2b = -5
2b = -5 - 3 = -8
b = -4
Also b = c, so c = - 4
Answer: a = 3, b = -4 and c = -4
Answer:
8 1/4
Step-by-step explanation:
3/4= 9in
11/12= 11in
9x11=99 in
99/12=8.25
8 1/4
I don't know how to do this but if it's a website At the top of the paper where ur teacher printed it from it might have the answer key
