Answer:

Largest angle is 105°

Smallest angle is 21°

The second angle is 54°

Step-by-step explanation:

Let the largest angle be x°

The smallest angle will be 1/5x°

The second angle will be x° - 51°

Angles in a triangle add up to 180° so;

x + x - 51 + 1/5x = 180

11/5x = 180 + 51 , 11/5x = 231 , x = 105°

Smallest angle is 1/5 × 105 = 21°

The second angle is 105 - 51 = 54°

I need help please and thank you and show work

Answer:

Ivy is correct

Step-by-step explanation:

the perimeter of a parallelogram can be written as P= 2(a+b), where a and b are the lengths of the sides of the parallelogram.
since the parallelogram has been dilated by a scale factor of 0.6, we multiple the original side lengths by 0.6.
12 × 0.6 = 7.2
16 × 0.6 = 9.6
Plug into the equation
P=2(7.2+9.6)
P=2(16.8)

P= 33.6

You can also solve by plugging in the original values and multiplying the answer by 0.6.
P=2(12+16)(0.6)
P=2(28)(0.6)
P=(56)(0.6)

P=33.6

-8 -8x + 10 + 6x = 19
hram777 [196]

Answer:

x = -8.5

Step-by-step explanation:

Let's rearrange the question to find x :)

-8x + 6x + 10 - 8 = 19

-2x + 2 = 19

-2             -2

-2x = 17

/-2      /-2

x = -8.5
