Answer:
the question is not complete pls complete the question even though the formulas are lxb for rectangles area and SxS for squares area
Triangles= 180°
Add the 3 angles to equal 180°
17x + (10x - 5) + 50= 180
combine like terms
27x + 45= 180
subtract 45 from both sides
27x= 135
divide both sides by 27
x= 5
ANSWER: x= 5
Hope this helps! :)
Answer:y=2/3x-2
Step-by-step explanation:
you need to get “Y” by itself therefore you subtract 2x on each side you will end up with -3y=-2x+6 then to get “Y” by itself you divide by -3 on both side and since there is a negative 2 on the other side a negative and a negative makes a positive and then you divide the 6 by -3 , that will give you y=2/3x-2
Answer:
Step-by-step explanation:
Sin theta is the ratio of side opposite over hypotenuse of a reference angle situated at the origin in an x-y coordinate plane. If sec theta is negative, then the only quadrant where sin is positive AND sec is negative is quadrant 2. Remember that sec theta is the inverse of cos theta. Puttling our right triangle in QII, the side measuring 7 is across from the angle and the hypotenuse is 11. In order to find the cos theta and tan theta, we need the side adjacent to the angle. Use Pythagorean's Theorem to find the side adjacent.
and
and
so

Remember that this value is why the sec is negative. Because x is negative in QII, the cos theta is side adjacent over hypotenuse:
and

But we should probably rationalize that denominator, so
