Answer:
sin45×20
Step-by-step explanation:
Remember sin of an angle is the opposite side divided by the hypothenuse. Or the hyp isb20 so the oppside will be sin45 times the hyp
Let
x = number of tulips
y = amount of daffodils
We have the following system of equations:
x + y = 15
5x + 2y = 45
Solving the system
Step 1:
-5x + -5y = -75
5x + 2y = 45
Step 2:
-3y = -30
y = 30/3 = 10
Step 3:
x = 15-y
x = 15-10
x = 5
Answer:
she should use
10 daffodils
5 tulips
Step-by-step explanation:
angle A = angle B. ( corresponding angles of two parallel lines)
8x-8°=5x+25°
8x-5x= 25°+8°
3x=33°
x=11°
angle B= 5x+25°
= 5(11)°+25°
= 55°+25°
= 80°
