Answer:
jim is correct, x <em>does</em> equal 7°. justify your answer by putting seven back into the equation. it gives you back that 180 equals 180, therefore it is correct
Step-by-step explanation:
so, all angles of a triangle have to add up to 180;
(15x) + (8x - 11) + (3x + 9) = 180
15x + 8x - 11 + 3x + 9 = 180
add your common numbers
26x - 2 = 180
add 2
26x = 182
divide 26
x = 7
put it back into the equation
15(7) + 8(7) - 11 + 3(7) + 9 = 180
180 = 180

Answer:
4.69
Step-by-step explanation:
sin = opposite/hypotenuse
sin 23 = a/12
To solve for a, multiply both side by 12, so a is by itself.
12 · sin23 = a/12 · 12
12 · sin23 = a
use your calculator to find the sin of 23, which is approximately 0.390731128
Multiply by 12
0.390731128 * 12 = 4.688
