let the first angle be a

then

second angle= 68+a

third angle=2a

we know

a+b+c=180 [sum of interior angle of triangle is 180]

a+68+a+2a=180

4a=180-68

a=28

Hence

first angle=28

second angle = 96

third angle =56

A rectangle has a width of 44 centimeters and a perimeter of 180 centimeters what is the rectangle length
Mumz [18]
If the width of a rectangle is 44 cm, multiply that by 2 for the other side and you have 88. 180 - 88 = 92, so divide that by 2 for each side and the length is 46 cm.

So far you have completed 80% of the problems for your math exam. Your exam
zmey [24]

Answer:

Problems left to complete = 9

Step-by-step explanation:

Given that:

Number of problems on the test = 45

Percent of completed problems = 80%

Number of completed problems = \frac{80}{100}*45

Number of completed problems = 0.8 * 45 = 36

Problems left to complete = 45 - 36

Problems left  = 9

Hence,

Problems left to complete = 9
