Answer:
the first one is 90, the second is 150, the third is option dStep-by-step explanation:
Answer: 11
Step-by-step explanation:
Complementary angles mean both angles sum 90°, then:
(3x + 2)° + 5x° = 90°
3x° + 2° + 5x° = 90°
8x° + 2° = 90°
8x° = 88°
x = 11
Confirmation:
(3x + 2)° 5x°
(3(11) + 2)° 5(11)x°
(33 + 2)° 55x°
35°
35° + 55° = 90°
For this item, we represent first the proportionality constant by the variable k. Being directly proportional to both b and c, these variable will be in numerator and d will be in the denominator. That is,
a = kbc / d
Substituting the known values,
400 = k(16)(5) / (2)
The value of k is 10. The equation that models the relationship is therefore,
a = 10bc/d
wow thank you for this answer! :) it was right.
