Step-by-step explanation:
Ruler's formula states that
We also know that
therefore,
(1)
Similarly, we can write
(2)
Adding Eqn(1) and Eqn(2) together, we get
or
To get the expression for the sine function, we subtract Eqn(2) from Eqn(1) to get
or
Answer:
x = 38
Step-by-step explanation:
RT is a midsegment and is one half the measure of QU, thus
QU = 2RT, that is
x - 6 = 2(x - 22) ← distribute
x - 6 = 2x - 44 ( subtract x from both sides )
- 6 = x - 44 ( add 44 to both sides )
38 = x
Answer:
Step-by-step explanation:
First, find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:
Now input the slope into the Point-Slope Formula. In this formula, all negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT signs:
