How to find variables x- and y-

Mathematics
1 answer:
Monica [59]3 years ago
5 0

It says that the triangles are congruent (same size). Also, a triangle's angles add up to 180 degrees. In both of these triangles, one angle is 90° and another angle is 52°. The other angle is 180°-90°-52°=38°.

Solve these equations to find x and y: 2x+18=38, 3y+11=38

2x+18=38\\2x=20\\x=10

3y+11=38\\3y=27\\y=9

(0,3) and (2,4) are on the line
solniwko [45]
Slope-intercept form is y = mx + b

The slope can be found by dividing y(2) - y(1) by x(2) - x(1).

4 - 3 = 1
2 - 0 = 2
m = 1/2

Since the first point has an x-coordinate of 0, the y-coordinate is the y-intercept of the line.

b = 3

Equation: y = 1/2x + 3

What is the value of x?
Tanzania [10]

Answer:

16

Step-by-step explanation:

By the property of intersecting chords inside the circle, we have:

(5x - 7) \degree =  \frac{1}{2} (119 \degree + 27 \degree) \\  \\ (5x - 7) \degree =  \frac{1}{2}  \times 146 \degree\\  \\ (5x - 7) \degree = 73\degree \\  \\ 5x - 7 = 73 \\  \\ 5x = 73 + 7 \\  \\ 5x = 80 \\  \\ x =  \frac{80}{5}  \\  \\ x = 16

Seiki is planning her workout at her gym. She wants to spend more than 40 minutes exercising. Her workout plan includes 20 minut
Juliette [100K]

Answer:

Assuming that Seiki wants to be as close to 40 minutes are possible (to the nearest minute), She would want to spend 7 minutes on each of the 3 cardio machines

Step-by-step explanation:

With Seiki wanting to spend at least 40 minutes exercising and spending 20 minutes lifting weights, she needs to spend at least 20 more minutes on her cardio. If we are looking for a number that is divisible by 3, that would mean that she would spend 21 minutes exercising.

Carlos is packing bags for treats at a party. Every bag has exactly the same amount of treats in it. Carlos has 25 granola bars
Advocard [28]

Answer:

5 bags

Step-by-step explanation:

Given

Granola\ Bars = 25

Popcorn\ Balls = 35

Required

Determine the greatest number of bags

This question illustrates greatest common factor (GCF).

The number of bags will be solved by getting the GCF of 25 and 35.

This is shown below:

25 = 1 * 5 * 5

35 = 1 * 5 * 7

GCF = 1 * 5

GCF = 5

Hence, Carlos will need 5 bags
