Answer:
Step-by-step explanation:
area of triangular face = ½·3·4 = 6 cm²
area of 3 by 7 face = 3×7 = 21 cm²
area of 5 by 7 face = 5×7 = 35 cm²
area of 4 by 7 face = 4×7 = 28 cm²
total surface area = 2×6 + 21 + 35 + 28 = 96 cm²
Let the complement be “x”
Equation: x+8=90
x= 90-8= 82 degrees
I believe it's 5,6
Hope this helped!
Best choice for variables.....I would let students be " s " and parents be " p "
The amount paid each month is 1050.
35,000 plus 20% is 42,000 because 20% of 35,000 is 7,000.
Next, divide 42,000 by 20, and you would get 1050.
