1. use sin
inverse of sin(44/57) = 50.5 ---> 51°
2. use tan
inverse of tan(6/8) = 36.8 ---> 37°
3. use cos
inverse of cos(20/31) = 49.8 ---> 50°
4. use sin
inverse of sin(37/58) = 39.6 ---> 40°
M=9/2 sorry if it’s wrong
Answer: 12.263 sqm
Step-by-step explanation:
1 square meter = 10.7639 square feet
132 square feet in meters would therefore be;
1 sqm : 10.7639 sqf
x sqm: 132 sqf
10.7639x sqm = 132sqf
x sqm = 132 / 10.7639
= 12.263 sqm
Number 1:
9x^2 + 12x + 4 -> (3x + 2)^2
16x^2 + 24x + 9 -> (4x + 3)^2
2. x^2 + Bx + 64
B = (sqrt64) *2 = 16
3.
Solving equations like this requires completing the square, which has the first step of choice 4.
Answer:
x=38
Step-by-step explanation:
First, know that the sum of the angles in a triangle is 180.
Then, add the angles. 2x+38+x+x-10.
Make them equal to 180.
2x+38+x+x-10=180
Simplify.
4x+28=180
Subtract 28 from 180.
4x=152
Divide 4 from 152 to make x alone.
x=38
There you go!
