Use the figure below to complete the following problem. Given: H = 2x + 60 T = x + 30 HALT is a ∠H = 90 120 150

Pavlova-9 [17]

Answer:

∠H = 120

Step-by-step explanation:

See the attached figure

HALT is a parallelogram

So, angles H and T are supplementary.

∠H = 2x + 60 and ∠T = x + 30

∠H + ∠T = 180

∴ 2x + 60 + x + 30 = 180

∴ 3x + 90 = 180

∴ 3x = 180 - 90 = 90

∴ x = 90/3 = 30

So, ∠H = 2x + 60 = 2 * 30 + 60 = 60 + 60 = 120

A = length • width

A = 10 • 8 = 80

area that needs to be covered = 80 • 2 = 160 square inches

Step-by-step explanation:Let a be the length of line

from question we know that

a+3 is another line

Here

a+(a+3)=15. ( Given in question )

2a = 15 -3

2a=12

a=12/2

a=6

Here a and a +3 are the length of the line

Finally ,6 and 9 are the lengths
