Complementary angles add up to 90°. The complement of a 27° angle is 90°-27°= 63°.
Supplementary angles add up to 180°. The supplement of a 27° angle is 180°-27°=153°
<span>-28ab-35ab+12b^2-42b^2
add similar element=-</span>28ab-35ab=-63ab
so that..
=-63ab+12b^2-42b^2
add similar element=12b^2-42b^2=-30b^2
=-63ab-30b^2
Answer:
∠XYZ = 37.5
Step-by-step explanation:
IN THE IMAGE ABOVE
731=3x+2
731 - 2 = 3x+2 -2
729=3x
729/3 = 3x /3
243=x
We take the value of F in the inequality by taking the inequalities in group. Let the first group be:
(1) -20 ≤ 59(F - 32)
Then, the second group would be,
(2) 59(F - 32) ≤ - 15
Calculating for the values of F,
(1) -20 ≤ 59F - 1888
1888 - 20 ≤ 59F
1868 ≤ 59F
F ≥ 31.66
(2) (59)(F - 32) ≤ - 15
59F - 1888 ≤ -15
59F ≤ 1873
F ≤ 31.75
The values of F are therefore,
31.66 ≤ F ≤ 31.75
