What is the value of x in the figure shown below?

Mathematics
1 answer:
Zepler [3.9K]2 years ago
3 0

Answer:

75 degrees.

Step-by-step explanation:

The total number of degrees in a triangle is 180 degrees therefore you can take the sum of the other 2 angles in the triangle and take that number and subtract it from 180.

1). 30+75=105

2).180-105=75

3). using the Side, Side, Side geometry rule, this means that both triangles are the same for all angles and side lengths

4). using the Alternative angle rule, the rule that say that a line that intersects 2 parallel lines forms 4 pairs of similar angles

5). therefore angle ABC is the same as angle BCD

6). Angle ABC was determined to be 75 degrees therefore angle BCD is also 75 degrees

Christopher scored 7 more than two times the questions Mathew scored on the math test. If Christopher scored 87 on the math test
viktelen [127]

Answer:

40

Step-by-step explanation:

To solve this, we can create an equation that represents this situation. Since Christopher score 7 more than twice what Mathew scored, the equation will be:

C = 2M + 7

(Variables are representative of the first letter of each name)

Seeing as Christopher scored 87, we can put that into the equation and solve for M.

So, the equation will be:

87 = 2M + 7

Subtract 7 from both sides in order to isolate variable M on the right side.

80 = 2M

Now solve for M, which is 40 (divide both sides by 2).

Please help ^^^^^^^^ <br><br><br> a= 4, 7, 15?<br> b= 7, 15, 4?<br> c= 15, 4, 7?
zysi [14]

Answer:

A is 15, B is 1, and c is 4!

Step-by-step explanation:

This is because 15 (rooted number) would be the main focus, and since the x (normally by the rooted number) doesn't have a label (like 2x, 3x, etc.) it will be one. Then, the 4 (last number) is c (since it is on the outside and is likely the divisor.

Good luck!
