Answer:
a = -4
Step-by-step explanation:
To solve for 'a', isolate 'a'.
a - 15 = 4a - 3
Subtract '4a' from both sides,
a - 4a -15 = -3
Combine like terms,
-3a - 15 = -3
Add 15 to both sides,
-3a = -3 + 15
-3a = 12
Divide both sides by (-3),
a = 12 ÷ (-3)
Answer: H = 8 cm
Step-by-step explanation: Since a triangle's area is b times h/2, we know that two times 48 is 96, therefore we can opposite the equation so 12 is the base times the height (8 cm) is 96 divided by 2, there's your answer.
Angle A is 73 degrees.
This can be found by using the values for both angles and setting them equal to 180. Since they are alternating interior angles of intersections of parallel lines, they must equal 180.
6x - 35 + 3x + 53 = 180
9x + 18 = 180
9x = 162
x = 18
Since x = 18 we can place that into the equation for angle A in order to find it's value alone.
6x - 35
6(18) - 35
108 - 35
73
