Hello.
To find the value of the angle x, you need to use the Law of Sines. The Law of Sines states, sin A / a = sin B / b = sin C / c.
We are given sin A = 42 degrees, side a = 22 cm, and side b = 12 cm. We can change x, to angle B in this case.
sin (42) / 22 = sin B / 12 (multiply both sides by 12)
12 sin (42) / 22 = sin B
sin^-1 B = 12 sin (42) / 22
sin B = 21.4063..
The measure of angle x is equal to about 21.4 degrees.
Answer:
-3/5
Step-by-step explanation:
7 * -3/7 * 1/5
Rewritng
7/7 * -3/5 *1
Simplifying fractions
1 * -3/5 *1
-3/5
Answer:
1. 1 & 16, 2 & 8, 4 & 4
2. 1 & 39, 3 & 13
3. 1 & 50, 2 & 25, 5 & 10
if we put 0 and 1 for x then y will be :
hope this helps
Answer:
the answer is A. 2370 sq. in
Step-by-step explanation:
area of the triangles first
A = 1/2 ad
a = (45 in) (20 in)
a = 1/2 (900 sq in)
a = 450 sq in
***remember to multiply 450 * 2 because you have 2 triangles***
Total area of both triangles is 900 sq. in.
Find the area of the 3 rectangles A = LW
1st rectangle and 2nd rectangle
a = cb
a = (30 in) (14 in)
a = 420 sq in. (make sure you add this again in the Total Surface area)
3rd rectangle
a = ab
a = (45 in) (14 in)
a = 630 sq. in
Total Surface area = 2 (1/2 ad) + 2(cb) + (ab)
= 2 (450 sq. in) + 2 (420 sq. in) + 630 sq. in
= 900 sq. in + 840 sq. in + 630 sq. in
= 2370 sq. in
