Answer:

I think it's 45 degrees

Step-by-step explanation:

<c is 90 degrees and the interior of every triangle is 180 degrees so then we subtract 90 from 180 which is 90 so we divide 90 by two since b and a seem to be equal which is 45 degrees.

Answer:

Step-by-step explanation:

There are 4/4 to make a whole so 2 1/2 cups would be 10 'scoops' and 1 1/4 would be 5 'scoops'. Add 10 + 5 to get a total of 15 scoops.

Hope that helps and have a great day!

In DEF the measure of D is equal to 5 degrees more than the measure of E. The sum of the measures of D and E is 10 degrees more

Gelneren [198K]

Answer: Measure of angle E = 45°

Measure of angle D = 45°+5° = 50°

Measure of angle F = 85°

Step-by-step explanation:

Let the measure of angle E be x. ( in degrees)

Then Measure of angle D = x+5

Also, Angle D + Angle E = Angle F +10

$\Rightarrow\ x+5+x =\text{Angle F}+10\\\\\Rightarrow\ \text{Angle F} = 2x+5-10\\\\\Rightarrow\ \text{Angle F} = 2x-5$

Since DEF is a triangle, so the sum of their angles should equal to 180 degrees.

$\Rightarrow\ x+x+5+2x-5=180\\\\\Rightarrow\ 4x=180\\\\\Rightarrow\ x=45$

Measure of angle E = 45°

Measure of angle D = 45°+5° = 50°

Measure of angle F = (2(45)-5)° = (90-5)° = 85°

X = - y - 2 <br> 0.5x + y = 1

ivolga24 [154]

Answer:

Step-by-step explanation:

substitute x = - y - 2 in 0.5x + y = 1

0.5(- y - 2) + y = 1

-0.5y-1+y=1

0.5y=2

y=4

x=- y - 2

x=-4-2

x=-6
