Answer:
b=17.75 ft
Step-by-step explanation:
We will answer this using Pythagorean Theorem.
Since the bottom of a ladder is 3 feet from the wall, and the ladder is 18 ft long, the ladder is the hypotenuse. Knowing pythagorean theorem (a^2+b^2=c^2), we can plug it in.
3^2 + b^2 = 18^2
9+b^2=324
b^2=315
b=17.75 ft
G(5) = 2(5)-5=5
h(2)=4(2)+5=13
So, g(5)+h(2)=13+5=18.
A is on the graph. When you plug in 3 in for x you get -4
B is not. When 1 is plugged in you do notnget 4
Answer:
28 degrees
Step-by-step explanation:
Because a triangle equals 180, you can subtract 90 and 34 from triangle ABE to leave you with 56 degrees for angle B.
Since CBA is a straigth line with 180 degrees, you can subtract 56 to end up with 124 degrees for angle CBE.
Since line BD bisects angle EBC (splits in half), you can divide the 124 degrees into 62 degrees.
Now that we know angle CBE equals 62 degrees, we can add the 90 degrees and subtract them from the 180 degrees of the triangle.
62+90=152
180-152=28
