Can you please help me

Answer:

p = 4.0

q = 2.0

angle <P = 64 degrees

Step-by-step explanation:

We can use the definition of cosine to find the value of side p (the adjacent side to the 26 degree angle, via the formula:

$cos(26^o)= \frac{adjacent}{hypotenuse} \\cos(26^o)= \frac{p}{4.5}\\p= 4.5 *cos(26^o)\\p=4.0445$

which rounded to the nearest tenth gives : p = 4.0

Now we use the sine function to help us determine side q:

$sin(26^o)= \frac{opposite}{hypotenuse} \\sin(26^o)= \frac{q}{4.5}\\q= 4.5 *sin(26^o)\\q=1.9726$

which rounded to the nearest tenth gives:

q = 2.0

Finally, we determine the measure of angle P using the fact that the addition of all internal angles of a triangle must add to 180 degrees:

< P + < Q + < R = 180

< P + 26 + 90 = 180

< P = 180 - 26 - 90

< P = 64 degrees

to shift the graph of an equation a certain number of units down, you need to ______ the function equation

avanturin [10]

Answer:

Step-by-step explanation:

...You need to subtract that number of units from the function equation.

Example: given y = x^2, and wanting to shift the entire graph down 3 units, we subtract 3 from y = x^2, obtaining y = x^2 - 3.
