Answer:
Step-by-step explanation:
we know that the total angles around the big triangle are 180° so, we know the right angle is 90° and we are told that one of the angles is 52° so just find the last angle by
180 = 90 + 52 + X
180 - 90 - 52 = X
38 = X
b = 38°
a = 52°
Base - i cant tell if it’s multiplication or a decimal but if it’s a decimal base is 3.4 if it’s multiplication 12
height - 3.52
area - 1/2 x 3.4(might be 12) x 3.52 = 5.984
Answer:
solving by substitution: t = -9, r = -6
Step-by-step explanation:
$169, you do 10% and times it 3 times to get 30 then add 9
Here you go . 146 is the answer with the work shown.
