Answer:

m∠P =119

m∠Q = 61

Step-by-step explanation:

m∠P =  2(∠Q)-3    or p=2(q)-3

supplementary angles so they combine to equal 180!

soooooo we can take  

q+p=180

input what p equals and you get

q+ 2(q)-3=180

3q-3=180

3q=183

q=61

now we have what m∠Q is, so just subtract that from 180 to get m∠P

180-61=119

What is measure of side A?
Ira Lisetskai [31]

<u>Answer:</u>

The correct answer option is c. a = 11.94.

<u>Step-by-step explanation:</u>

We are given a right angles triangle with an angle ABC equal to 58 degrees and side length AC known to be equal to 19.1.

We are supposed to find the length of side a.

Side AC, opposite to angle ABC, will be the perpendicular and BC will be the base so we will use the formula of tan to find b.

tan 58 = \frac{19.1}{a}

a = \frac{19.1}{tan 58}

a=11.94

Solve for x 14 x square+7x-6
irina [24]

Answer:

x=0.450765 or x=−0.950765

Step-by-step explanation:

14x² + 7x - 6

→ Find the product, sum and factors

Product = -6

Sum = 7

Factors = No factors

→ Since there are no factors utilise the quadratic formula

\frac{-b+-\sqrt{b^{2}-4ac } }{2a}

→ List the values of a, b and c

a = 14

b = 7

c= -6

→ Substitute into the formula

\frac{-7+-\sqrt{7^{2}-4*14*-6} }{2*14}

→ Simplify

x=0.450765 or x=−0.950765
