Complementary angles add up to 90°
m∠4 = 49° then m∠3 = 41°
49 + 41 = 90

Answer:
5√13 = c OR 18. 0
Step-by-step explanation:
Using the Pyhtagorean Theorem, we will solve for x (in this case our hypothenuse)
a2 + b2 = c2
10(square) + 15(square)= c2 .....10*10 = 100 and 15* 15= 225
100 + 225 = c2
325= c2
√325 = c
5√13 = c OR 18. 0
Answer:
The intercepts 
Step-by-step explanation:
Given:
Required
Determine the intercepts
The equation is a linear equation and the intercepts of the equation is calculated as thus;
For x intercepts; substitute 0 for y
Add 1 to both sides
Divide both sides by 4
Simplify fraction to lowest term
For y intercept, substitute 0 for x
Subtract 5 from both sides
Divide both sides by 3
Reorder
Hence, the intercepts
Answer: B. 2 = 3x + 10x2
Step-by-step explanation:
This is the concept of quadratic equations; We required to find the type of equation that can be solved using the model that has been used to solve the equation such that the answer is:
[-3+-sqrt(3^2+4(10)(2))]/(2(10))
The formual that was applied here was a quadratic formula given by:
x=[-b+\-sqrt(b^2-4ac)]/2a
whereby from the our substituted values above,
a=10,b=3 and c=-2
such that the quadratic equation will be:
10x^2+3x-2
