Answer to problem 5 is A) WU = ZX.
Notice how the angle U is between WU and VU. Similarly, angle X is beween ZX and XY
The order is very important. The angles must be between the two pairs of sides.

Answer to problem 6 is C) 15/17.
Use the pythagorean theorem to find the hypotenuse AC to be 17 units. Then take the ratio of the adjacent and hypotenuse to get the answer.

Answer to problem 7 is choice C
Use the rule cos(90-x) = sin(x) where x = 72-a
Answer:
there is 140 of raisins and 350 of aimonds and identical 490
Step-by-step explanation:
Answer:
The measure of C is 75 degrees
Step-by-step explanation:
Since ABC is isosceles, we know that C is equal to B. Therefore, we can add all the angles together and set equal to 180 to find the value of x.
A + B + C = 180
x + 5 + 3x + 3x = 180
7x + 5 = 180
7x = 175
x = 25
Now we can plug in the value of x into 3x to find C.
C = 3x
C = 3(25)
C = 75
Third is y=-2x-2, second is y+4=-1(x-3), first is y+5=-1(x+4)
Answer:
1.84ft
Step-by-step explanation:
From the figure attached,
AB = Height of the window = 15ft
Let the distance between the base of the housr and the fence 'C' = xft
If the angle of depression = 7°
Then angle of elevation of the top of the fence from the house = 7°
Now from right triangle ABC,
tan7° = x/15
x = tan7°×15
x = 0.1227×15
x = 1.84ft
Therefore, distance of the house from the fence is 1.84ft
