Yo sup??

by angle sum property we know that the sum of all angles in a triangle is 180

let the unknown angle be x

then,

x+60+90=180

x=180-150

x=30

Hope this helps

The sum of the angles of a triangle is 180°.

The angle measures you know are 60° and 90° (because the box in the top right corner of the triangle means that it is a right angle, which equals 90°). So you can do this to find the missing angle:

60° + 90° + ? = 180°    Add 60 and 90

150° + ? = 180°     Subtract 150 on both sides

? = 30°  The missing angle is 30°

Write an exponential function whose graph contains the points (1, 6) and (0, 2).
12345 [234]

Answer:

y = 2 (3)^{x}

Step-by-step explanation:

The exponential function is of the form

y = a (b)^{x}

To find a and b substitute the given points into the equation

Using (0, 2), then

2 = a (b)^{0} ⇒ a = 2

Using (1, 6), then

6 = 2 (b)^{1} ⇒ b = 3

Equation is y = 2 (3)^{x}

Multiply and simplify out theese brackets(X+1)(x+3)
Lorico [155]
The method in which you do this problem would be to FOIL. First Outer Inner Last. You take the first terms and multiply them. x*x = x^2 (x to the second power). Then you do it with the rest of foil.
x*x = x^2
x*1 = x
x*3 = 3x
1*3 = 3
x^2 + x + 3x + 3 = X^2 + 4x + 3
