The measures of two supplementary angles have a ratio of 4: 5. what is the measure of the larger angle

The measure of the larger angle = 100°

Step-by-step explanation:

∵ The measure of the supplementary angles = 180°

∵ The ratio between them is 4 : 5

Let the smaller is 4x and the larger is 5x

∴ 4x + 5x = 180

∴ 9x = 180°

∴ x = 180 ÷ 9 = 20

∴ The measure of the larger angle = 5 × 20 = 100°

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

e) none of the above because the measure of angle cba is 101°
