Find the measurement of angle A
yaroslaw [1]

Answer:

The value of A is 20

Step-by-step explanation:

To find the answer, note that all triangles have a interior degree measurement of 180. Set the sum of the angles equal to 180.

71x - 1 + 20x + 90 = 180

91x + 89 = 180

91x = 91

x = 1

Now we can use this in the A angle to find the value.

A = 20x

A = 20(1)

A = 20

Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing,
alina1380 [7]

Answer:

We are have the function f(x).

Part 1: It is given that the function f(x) is transformed to f(x)+2.

This gives us that the function is translated 2 units upwards.

As, the y-intercept of f(x) is f(0). So, the y-intercept of f(x)+2 is f(0)+2, which is also translated 2 units up.

Translation does not change the behavior of the function.

So, if f(x) is increasing (or deceasing), then f(x)+2 will be increasing(or decreasing) respectively.

Moreover, f(x)+2 will be even or odd if f(x) is even or odd respectively.

Part 2: It is given that the function f(x) is transformed to \frac{-1}{2}f(x)

This gives us that the function is shrinked vertically by a factor of \frac{1}{2} followed by a reflection across x-axis.

Also, the y-intercept of is \frac{-1}{2}f(0).

The graph of f(x) after changing to \frac{-1}{2}f(x) will flip over the x-axis.

So, the function \frac{-1}{2}f(x) will increase or decrease when f(x) decrease or increase respectively.

Moreover, \frac{-1}{2}f(x) will be even if f(x) is even or odd respectively.

Find the length of the third angle of a triangle given that the first two angles are 35 and 70.
ss7ja [257]
Hi,

the interior angles of a triangle always add up to 180 degrees. Therefore 35 + 70 + ? = 180.
so, 35+70 = 105. 180-105= 75 degrees.
