Answer:
PR = 6.9
Step-by-step explanation:
From the diagram, the following were obtained:
Hypo = 10
Opp = PR
Sin0 = 44°
Sin0 = opp /Hypo
Sin44° = PR/10
Cross multiply
PR = 10 x Sin44°
PR = 6.9
Answer:
sin44 = PR÷PQ = 0.694÷1 × X÷10 = X = 6.94

Answer : The Celsius temperature is, 50 degree.
Step-by-step explanation :
Formula used :
where,
c = Celsius temperature
f = Fahrenheit temperature
As we are given that the Fahrenheit temperature is 122 degree. Now we have to determine the Celsius temperature.
Now put the value of Fahrenheit temperature in above formula, we get:
Thus, the Celsius temperature is, 50 degree.
The required Celsius temperature for a Fahrenheit temperature of 122 degrees is 50 degrees Celsius.
To find the Celsius temperature for a Fahrenheit temperature of 122 degrees, we can use the given formula: c = 5(f - 32) / 9.
Substituting the Fahrenheit temperature of 122 degrees into the formula, we have:
c = 5(122 - 32) / 9.
Now we can simplify the expression:
c = 5(90) / 9,
c = 450 / 9,
c = 50.
Therefore, the Celsius temperature for a Fahrenheit temperature of 122 degrees is 50 degrees Celsius.

1. supplementary
28 + x = 180
subtract 28 from each side
x = 152°
m<FEG = 152°

8. < YOZ is a right angle, so <YOZ = 90°
< WOX is complementary to the 40° angle.
< WOX + 40 = 90
< WOX = 50°
< XOZ can be found by adding together the 40° and < YOZ.
40 + 90 = < XOZ = 130°

each side appears twice so the total area A will be
A=2(length*width+width*height+height*length)=16*8+8*4+4*16
A=224
If you meant lateral area as in the total area minus the top and bottom base:
A=2(width*height+height*length)=8*4+4*16=96
