2nd is -3x -2
3rd one (put 1 instead of x in the given functions then calculate values and multiple )6
Answer:
8
Step-by-step explanation:
AC=AB+BC
2X+26=1+x+16
2x-x=1+16-26
X= - 9
Now, AC=2X+26
=2*-9+26
= - 18+26
=8
Answer:
I think your answer is 85. The 50 degree angle on the left side of E is equal to the angle to the right of E. Since both triangles have equivalent angle measurements, D and B are correspondent of one another. Add the 50 degrees to the 45 degrees to get 95. Since triangles total measurements equal 180, subtract 95 from 180 to get 85. Angle D = 85, and since Angle B is correspondent, Angle B = 85°
Answer:
14
Explanation:
Given:
Volume of the prism = 3360 units^3
To find:
The height of the prism
We'll use the below formula to determine the height(h) of the prism;
So the height of the prism is 14
Given that <span>cos a = 3/5 and it is in the first quadrant :
then:
a=arccos 3/5
but
cot </span>θ=1/tan θ
thus to evaluate our vale we shall obtain the value for height since
adjacent=3
hypotenuse=5
thus
using Pythagorean theorem:
c²=a²+b²
hence
5²=3²+b²
b²=25-9=16
b=4
thus
tan θ=opposite/adjacent
tan a=4/3
thus
cot a=1/(4/3)=3/4
