Answer:
x = 900/ 10 + 3fo
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Hello
<span>2(x-3)+5=4-7(2x-1)
2x-6+5 = 4 -14x+7
2x+14x =6-5+4+7
16x=12
x=12/16
x=(4×3)/(4×4)
x=3/4 (simplified by 4)
answer B</span>

-2(-5)+7=17
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given
Required
The measure of each angle
First, we calculate the length of the three sides of the triangle.
This is calculated using distance formula
For AB
So:
For BC
For AC
So, we have:
By representation
So, we have:
By cosine laws, the angles are calculated using:
Collect like terms
Solve for
Take arc cos of both sides
Collect like terms
Solve for
Take arc cos of both sides
For the third angle, we use:
--- angles in a triangle
Make C the subject
