Two parallel lines are crossed by a transversal. what is the value of a? a = 43 a = 63 a = 117 a = 137 two parallel lines are crossed by a transversal. bwhat is the value of h? h = 60 h = 80 h = 100 h = 120two parallel lines are crossed by a transversal. cwhat is the value of b? b = 32 b = 52 b = 118 b = 128

Part a) What is the value of a?

we know that

m∠a= -------> by corresponding angles

therefore

the answer part a) is

m∠a=

Part b) What is the value of h?

we know that

m∠h+ ---> by consecutive interior angles (supplementary angles)

m∠h=

m∠h=

therefore

the answer part b) is

m∠h=

Part c) What is the value of b?

we know that

m∠b= -------> by alternate interior angles

therefore

the answer part c) is

m∠b=

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

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.
