Find the measure of ∠P
Elenna [48]
To find the third angle of a triangle you can remember that ALL triangles angles add up to 180 degrees, ALWAYS

So that means that p + r + q = 180

r + q = 95

67 + 28 = 95 

So 95 + p = 180

We can subtract 95 from 180 to find what’s left so 180 - 95 = 85

The correct answer would be that the measure of angle p = 85 degrees

Because 28 + 67 + 95 = 180

I hope this helps! Dont forget to thank my answer and mark it as the brainliest if it was the most helpful! <3

20 POINTS!!! Use the quadratic formula above to solve for h(t) = -4.9t^2 + 8t + 1 where h is the height of the ball in meters an
Elina [12.6K]

Answer:

Two solutions: -0.12 and 1.75.

Step-by-step explanation:

The quadratic formula is:

\begin{array}{*{20}c} {\frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}} \end{array}. Assuming that the x² term is a, the x term is b, and the constant is c, we can plug the values into the equation.

\begin{array}{*{20}c}{\frac{{ - 8 \pm \sqrt {8^2 - 4\cdot-4.9\cdot1} }}{{2\cdot-4.9}}} \end{array}

\begin{array}{*{20}c}{\frac{{ - 8 \pm \sqrt {64 + 19.6} }}{{-9.8}}} \end{array}

\begin{array}{*{20}c}{\frac{{ - 8 \pm \sqrt {83.6} }}{{-9.8}}} \end{array}

\begin{array}{*{20}c}{\frac{{ - 8 \pm \sqrt {9.14} }}{{-9.8}}} \end{array}

\frac{-8 + 9.14}{-9.8} = -0.12

\frac{-8-9.14}{-9.8} =1.75

Hope this helped!

Simplify: 70x/2x.<br> A. 32<br> B. 33<br> C. 34<br> D. 35
Tresset [83]
The answer is D. 35. The x’s cancel out because x divided by x is 1 leaving you with 70/2 which is then 35.
Hope this helped.
