Step-by-step explanation:
10.if an angle is twice its complement you can represent the angle as x and other as 2x . since they are complement , there sum is 90 degrees . this means that one angle is 30 deg. the angle that is twice that value is 60 degrees.
11. 9/3×2×3 = 54
12. Let the ∠x be the required angle
Thus, according to the question
180−x=3(90−x)
=>180−x=270−3x
=>2x=90
=>x=45
13. Supplementary angles add to 180 degrees, so the supplement of angle x is 180 - x. Complementary angles add up to 90 degrees, so the complement of x is 90-x. Supplement is 120, complement is 30, 120 is four times 30.
14. If the ratio of the angles is 5:1, we need to divide 90° into 6 parts, of 15° each. The larger angle will be 5 × 15° = 75°. The smaller angle will be the remaining 15°.
