Answer:
8 portraits are going to be used in the display.
Step-by-step explanation:
This problem can be solved as a rule of three problem.
Each yd has 36 inches.
The display is to span a total width of 10 yd. So it is a total width of 360 inches.
Each portrait has a width of 45 in. How many portraits can there be?
1 portrait - 45 in
x portraits - 360 in
8 portraits are going to be used in the display.
ANSWER: a=12 b=15
Explanation: (look at work below)
4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15
X = arctan(32/19)
x = 59.30 degrees.
You don't say if the answer needs to be rounded, so round it as needed.
