Answer:
71 degrees
Step-by-step explanation:
A right angle is 90 degrees, so the answer is 90-19=71 degrees.
Answer:
x=21.35764429=21.4
Step-by-step explanation:
Take SOHCAHTOA
in this problem you're going to use SOH, which is sine= opposite/hypotenuse
sin31=11/x
Multiply by x as a way to isolate it
x(sin31)=11
divide my sin31 to isolate x
x=11/sin31
x=21.35764429
Answer:
558, 500
Step-by-step explanation:
round 349,001 to 349,000 subtracted 1
round 209, 499 to 209, 500 added 1
349,000 + 209, 500 = 558, 500
Now, the added and subtract 1 cancel out so that is the final answer
Y α xz
y = kxz y = 72, when x = 6, and z = 4
72 = k*6*4
72 = k*24
24k = 72
k = 72/24
k = 3.
<span>y = kxz
</span>
<span>y = 3xz </span>
Finding y, when x = 3, z = 5.
y = 3xz
y = 3*3*5
y = 45
So this is an algebra question, where you have have to setup the equation. Let t represent the number of hours.
36 + 8.80t < 115.20 we can then setup the equation like this to solve for the max hours.
36 + 8.80t= 115.20
Now solve
8.80t = 115.2-36
8.80t= 79.2
t = 9
so t < 9
