For the right triangles below, find the values of the lengths a and c. Round your answers to the nearest tenths

a=7.1

b = 4.6

Step-by-step explanation:

For the first triangle,

taking 45 as reference angle,

cos45 = b/h

or, cos45 = 5/a

or, a = 5/cos45

so, a = 7.07

so, a = 7.1

Again,

taking 60 as reference angle,

tan60 = p/b

or, tan60 = 8/c

or, c = 8/tan60

so, c = 4.6

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
