Answer:
Step-by-step explanation:
Picture 1
In right triangle ABC,
Side AB is the opposite side of angle C.
Picture 2
In triangle MKL,
tan(∠M) = 
= 
= 
Option (1) is the answer.
Picture 3
In ΔXYZ,
sin(∠Z) = 
= 
For the length of XY we will apply Pythagoras theorem in ΔXYZ,
XZ² = XY² + YZ²
XY² = XZ² - YZ²
= (40)² - (32)²
XY = √576
= 24
sin(Z) =
sin(Z) =
Picture 4
In right triangle DEF,
Cos(D) = 
= 
= 
= 
Picture 5
In ΔABC,
tan(63°) = 
tan(63°) = 
AB = 
AB = 
AB = 4.0762 ≈ 4 m
Option (3) will be the answer.
Answer:
C. 10.5 pounds
Step-by-step explanation:
The worth of 3 loaves of bread is 3 times that of one loaf:
3 × 1.75 = 5.25
You want the number of pounds of oranges (p) at 0.50 per pound that has this same worth:
0.50p = 5.25
p = 5.25/0.50 = 10.50
10.5 pounds of oranges have an equivalent cost to 3 loaves of bread.
