Answer:
E. 35°, 70°
Step-by-step explanation:
Sum of angles add up to 180° in every triangle.
Step 1: Set up equation
a + 2a + 75 = 180
Step 2: Combine like terms
3a + 75 = 180
Step 3: Subtract 75 on both sides
3a = 105
Step 4: Divide both sides by 3
a = 35
So 1 angle is 35°
Step 5: Plug in <em>a</em> to find last angle
2(35) = 70°
3/8 cannot be simplified into a smaller fraction. 3/8 in decimal form is 0.375.
She can buy 5 songs and still have 7 dollars left
5 + 2 = 7
7 x 5 = 35
Less than 40
7 x 6 = 42
But this is too much
So it would be 5 songs he could buy and still have $7 left. ( 7 x 5 = 35 )
