I have solved the first one. Hope this helps
let's set up an equation
4x=24
solve normally:
x=6
so the expression is 4x=24 and she can have 6 kids in each group
Answer:
A) y = 4/3 x - 1/3
Step-by-step explanation:
(4,5) and (-2,-3)
Slope = (5 + 3)/(4 + 2)
= 8/6
= 4/3
Equation
y + 3 = 4/3(x + 2)
y + 3 = 4/3 x + 8/3
y = 4/3 x + 8/3 - 9/3
y = 4/3 x - 1/3
Answer:
y = 4/3 x - 1/3
Answer:
A. The reference angle should be pi/3, and the sign of the value should be negative.
Step-by-step explanation:
Just took the unit review.
5. m∠C = 95°
6. m∠C = 70°
7. The other acute angle in the right triangle = 70°
8. m∠C = 70°
9. m∠C = 60° [equilateral triangle]
10. Measure of the exterior angle at ∠C = 110°
11. m∠B = 70°
12. m∠Z = 70°
<h3>What are Triangles?</h3>
A triangle is a 3-sided polygon with three sides and three angles. The sum of all its interior angles is 180 degrees. Some special triangles are:
- Isosceles triangle: has 2 equal base angles.
- Equilateral triangle: has three equal angles, each measuring 60 degrees.
- Right Triangle: Has one of its angles as 90 degrees, while the other two are acute angles.
5. m∠C = 180 - 50 - 35 [triangle sum theorem]
m∠C = 95°
6. m∠C = 180 - 25 - 85 [triangle sum theorem]
m∠C = 70°
7. The other acute angle in the right triangle = 180 - 90 - 25 [triangle sum theorem]
The other acute angle = 70°
8. m∠C = 180 - 55 - 55 [isosceles triangle]
m∠C = 70°
9. m∠C = 60° [equilateral triangle]
10. Measure of the exterior angle at ∠C = 50 + 60
Measure of the exterior angle at ∠C = 110°
11. m∠B = 115 - 45
m∠B = 70°
12. m∠Z = 180 - 35 - 75
m∠Z = 70°
