Answer:
180
Step-by-step explanation:
From basic rules of a triangle we know that the interior angles of a triangle have to add up to equal 180°
But here is a formula for future references for finding the sum of the interior angles
interior angle sum = (n-2)180
where n = number of sides
and here is an example:
a triangle has 3 sides so we plug in 3 for n
(3-2)180
3-2=1
1*180 = 180
so the interior angles add up to equal 180
<h3><u>The x intercept is -4.</u></h3>
To find the x intercept, all we need to do is replace the value of y with 0.
2x + 4(0) = -8
Solve for x.
2x = -8
Divide both sides by 2.
x = -4.
Answer:
20% tip.
Step-by-step explanation:
4.5/22.5=.2
Tip=0.2
Step-by-step explanation:
- 254.34
- i don't know the answer
Firstly you do: 28 divided by 7 (amount of children in ratio) this gives you 4. Then you multiply 4 by 2 to get the amount of adults. Your answer should be 8 adults.
