What is m<1 in this parallelogram

Xelga [282]

Answer:

Step-by-step explanation:

a parallelogram, with angles <1, (3m+20)° and 5m°.

Please note: The sum of adjacent angles of a parallelogram are supplementary that is sum equal to 180° and opposite angles are equal.

(3m+20)° + 5m° = 180° and < 1 = (3m+20)°

Solving equation (3m+20)° + 5m° = 180° for m.

3m +20 +5m = 180

Combining like terms, we get

8m +20 = 180.

Subtracting 20 from both sides, we get

8m +20-20 = 180-20

8m = 160

Dividing both sides by 8, we get

8m/8 = 160/8

m = 20

Plugging m=20 in 3m+20, we get

3(20)+20 = 60+20 = 80°

Therefore, <1 = (3m+20)° = 80°.

Which equation can be used to solve the problem? 180 is 40 percent of what number?

olga nikolaevna [1]

Answer:

720.

Step-by-step explanation:

So, 10% of 180 is 18, so x 18 by 40 is 720, (do the reversed operation) which will give you your answer..

Or you could go 10% of 40 which is 4, and then do 180 x 4, which will also give you a answer of 720.

Hope one of these helps! Xo

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (-1, -3.75)

Point (-1, 4.5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-1--1)^2+(4.5--3.75)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(0)^2+(8.25)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{0+68.0625}$
[√Radical] Add: $\displaystyle d = \sqrt{68.0625}$
[√Radical] Evaluate: $\displaystyle d = 8.25$
