Answer:
x = 21
Step-by-step explanation:
Multiply both sides by 16
3/4 x 16 = x - 9
2 Simplify 3/4 x 16 to 48/4
48/4 = x - 9
3 Simplify 48/4 to 12
12 = x - 9
4 Add 9 to both sides.
12 = x - 9
5 Simplify 12+9 to 21
21=x
6 Switch sides.
Answer: x=21

The factoring of the difference of squares is applicable:
a^2 -b^2 = (a -b)(a +b)
Answer:
The angles are 2x= 2x18°
=36° and 3x=3×18
=54°
Step-by-step explanation:
It is given that two complementary angles are in the ratio 2:3.
Consider 2x and 3x as the angles.
We know that, if two angles are complementary, then their sum is 90° .
Then, 2x+3x=90°
⟹ 5x=90°
⟹ x= 90/5
x=18°
Here, the angles will be 2x=2×18
°=36°
and 3x=3×18° =54 °
Hope this helps.
Answer:
Step-by-step explanation:
If you cut the square apart along a diagonal, you'll then have two isosceles triangles. Each such triangle will have 3 sides and 3 angles.
