<h3>Answer: 1.15</h3>
==============================================================
Work Shown:
QR = 73
QP = 55
PR = x
Pythagorean Theorem
a^2 + b^2 = c^2
(QP)^2 + (PR)^2 = (QR)^2
(55)^2 + (x)^2 = (73)^2
3025 + x^2 = 5329
x^2 = 5329-3025
x^2 = 2304
x = sqrt(2304)
x = 48
PR = 48
----------
tan(angle) = opposite/adjacent
tan(R) = QP/PR
tan(R) = 55/48
tan(R) = 1.1458333 approximately
tan(R) = 1.15
Answer:
C
Step-by-step explanation:
y=mx+b, where x any are variables, m is the slope and b is the y-int.
Step 1: Find the y-int
y-int = 3.25 (13/4)
Step 2: Find the slope using RISE/RUN
-13/7
Answer is C
Hope that helps
Y=20x+50
Y is the total cost and x is the number of hours
Answer:
49.4 degrees
Step-by-step explanation:
SOHCAHTOA
tan x = opposite / adjacent
tan x = 7 / 6
using graphing calculator, you get x = 49.398 round to tenth = 49.4 degrees
