Answer:

36.87° and 53.13°

Step-by-step explanation:

the legs of the right triangle are 3 and 4 and the hypotenuse is 5

tan x = 3/4

x = arctan (3/4)

= 36.87° = measure on one acute angle

90 - 36.87 = 53.13° = measure of the other acute angle

Solve for each variable.

dem82 [27]

Answer:

a = 38⁰

b = 54⁰

c = 54⁰

Step-by-step explanation:

a + 142⁰ = 180⁰ because a straight line = 180⁰

b + 38⁰ + 88⁰ = 180⁰ because the angles of a triangle equal 180⁰, and the missing measurement = 38⁰ because it is a vertical angle to angle a

c + 88⁰ = 142⁰ because the angles are corresponding angles

yulyashka [42]

Answer:

b = 5.

Step-by-step explanation:

-3(6 + 6b) + 4 = -104

-18 - 18b + 4 = -104

-18b = -104 + 18 - 4

-18b = -90

b = -90 / -18

b = 5.
