Find the value of z and y

Mathematics
2 answers:
Triss [41]2 years ago

Answer:

z = 50 .  y = 20

Step-by-step explanation:

y = 20 (due to vertically opposite angles)

20 + 5(20) + 10 + z = 180 (basically a straight line)

20 + 10 + 100 = 130

180 - 130 = 50

z = 50

Extra: If you need x,

90 + 20 = 110

180 - 110 = 70

x = 70

Answer: y=20, z=50

Step-by-step explanation: So first y is equal to 20 because of vertical angles.

and if we know y is 20 then we do the equation

20+z+5(20)+10=z+130

and since we know line segment DA is a straight angle it is 180 degrees.

180-130 will be 50 so you got 50 degrees for z

A long distance runner starts at the beginning of a trail and runs at a rate of 4 miles per hour. two hours later, a cyclist sta
valina [46]

To solve this problem, let us first assign variables. Let us say that:

A = runner

B = cyclist

d = distance

v = velocity

time = t

 

The time in which the cyclist overtakes the runner is the time wherein the distance of the two is the same, that is:

dA = dB

 

We know that the formula for calculating distance is:

d = v t

therefore,

vA tA = vB tB

 

Further, we know that tA = tB + 2, therefore:

vA (tB + 2) = vB tB

4 (tB + 2) = 14 tB

4 tB + 8 = 14 tB

10 tB = 8

tB = 0.8 hours = 48 min

 

Therefore the cyclist overtakes the runner after 0.8 hours or 48 minutes.

Given the function f(x) = 3|x – 2| + 6, for what values of x is f(x) = 18?
Nikolay [14]

Answer:

x = -2, x = 6

Step-by-step explanation:

18 = 3|x - 2| + 6

12 = 3|x - 2|

4 = |x - 2|

4 = x - 2    and    -4 = x - 2

x = 6    and    x = -2
