Answer:
It's ÷ (divide)
Step-by-step explanation:
Because 48+27 is 75, and 750÷10 is also 75.

Keep in mind that:
- the sum of the interior angles of every triangle in existence is 180 degrees
- the base angles of isosceles triangles are congruent
With this information, I have created a diagram. I encourage you to always draw a diagram when you can - it aids in the solving process.
Now, to find <em>a</em>, set the measures of the interior angles equal to 180.
(<em>a</em> + 15) + 7<em>a</em> + 7<em>a</em> = 180
Solve for <em>a</em>.
<em>a</em> + 15 + 7<em>a</em> + 7<em>a</em> = 180
15 + 15<em>a</em> = 180
15<em>a</em> = 165
<em>a</em> = 11
Find the angle measures by plugging 11 for <em>a</em>.
<em>a</em> + 15
(11) + 15
26
7<em>a</em>
7(11)
77
Check your work by adding the angles measures.
77 + 77 + 26 = 180

Answer:</h3>
<em>a</em> = 11
Each base angle measures 77 degrees and the vertex angle measures 26 degrees.
We know that 36 students make up 30 percent of all students who pick milk. We need to find the total number of students who pick milk. Let's solve for this total, t:
There are 120 students that pick milk with their lunch.
Answer: Nadia’s equation should be V = 1/2(12.5)(6.7)(20)
Leo’s equation: V = 1/2(21)(7)(29)
Darcie: V = 1/2(13)(4)(19)
Explanation:
The formula for the volume of a triangular prism = 1/2(base)(height)(length)
They meet (or pass) each other two hours after B leaves.
When B starts trip A has already gone 23 miles (46 x 0.5)
This means they are still 220 miles apart.
Their closing speed is 46 + 64 = 110 mph.
They will meet 2 hours after B leaves home. (220 / 110)
A will have travelled 46 x 2.5 = 115 miles and B will have travelled 2 x 64 = 128 miles
