Answer:

∠ABC= 40°  ∠CBD=60°  ∠EBD=80°

Step-by-step explanation:

Step 1: 2x+3x+4x=180

          A straight line is 180 degree's, and to get the value of the different angles, you have to add the three angle measures.

Step 2: 9x=180

            Combine like terms

Step 3: x=20

            Divide/ Isolate the variable

Step 4: 2(20)=40   3(20)=60    4(20)=80

           Plug the answer back in

The fur. h is defined by the following rule.h(x) = 6*Find h(x) for each x-value in the table.X76 FSunny-2-12Explanation0000Check
muminat

Given the function:

h(x)=6^x

It's required to find the values of h for x = {-2, -1, 0, 1, 2}.

For x = -2:

h(-2)=6^{-2}=\frac{1}{6^2}=\frac{1}{36}

For x = -1:

h(-1)=6^{-1}=\frac{1}{6^1}=\frac{1}{6}

For x = 0:

h(0)=6^0=1

For x = 1:

h(1)=6^1=6

For x = 2:

h(2)=6^2=36
