Geometry Isosceles and Equilateral Triangles Plsss help me ASAP!!!!

CaHeK987 [17]

Answer:

1. x = 10

(triangle has equal side lengths)

2. x = the same number inside the triangle

(is that a 40 or 80?)

3. x = 34

(is that a 34?)

4. x = the number shown on the other side of the triangle

(is that a 55?)

5. if the given number is 8 then x = 11

(11-3=8)

6. x = 11

(2x-15=7)

7. x = 5

(65+5=70)

8. x = 10

(5x-10=40)

9. m<2 = 9

(7x-3=60)

10. m<2 = 8

(x+72=80)

hope this helps!

Dividing mixed fractions

Sonbull [250]

A) 2 1/3 = 7/3
7/3 / 1/4 = 7/3 x 4/1 = 28/3 = 9 and 1/3

b) 4 2/5 = 22/5
1 1/5 = 6/5
22/5 / 6/5 = 22/5 x 5/6 = 110/30 = 3 and 2/3

PLEASE HELP!!!! Use the table below to match the slopes to the lines.

skelet666 [1.2K]

Answer: Check out the filled out chart below.

Row 1: 1/4, 1/4, -4

Row 2: -2, -2, 1/2

Row 3: 3, 3, -1/3

=========================================

Explanation:

Parallel lines have equal slopes. So if the original line has slope 1/4, then any parallel line will also have slope 1/4. The only thing different is the y intercept.

Perpendicular slopes multiply to -1 assuming neither line is vertical. For row 1, the perpendicular slope is -4 which multiplies with the original slope 1/4 to get -1.

Put another way, the perpendicular slope is the negative reciprocal of the original slope. For row 2, the perpendicular slope is 1/2 because we flip the fraction and the sign for the original slope -2 = -2/1
