Answer:
a = -10
Step-by-step explanation:
-0.4a + 3 = 7
subtract 3 from each side
-0.4a + 3-3 = 7-3
-.4a = 4
Divide each side by -.4
-.4a/ -.4 = 4/-.4
a = - 10
The answer is 8 because
8 times 4 = 32
8 times 7 =56
8 times 3 =24
56 minus 24 = 32
This triangle would be acute none of the angles are greater than or equal to 90.
