The ratio of two positive numbers is 3:4. The sum
of their squares is 400. What is the sum ofthe num-
bers?
Answer:
12 and 16.
Step-by-step explanation:
Let both positive numbers be x and y.
3/4 = x/y....... equation 1
x² + y² = 400..... equation 2
From equation 1
3/4 = x/y
Cross multiply
3y = 4x
Divide both sides by 3
y = 4x/3
Substitute y = 4x/3 into equation 2
x² + y² = 400
x² + (4x/3)² = 400
x² + 16x²/9 = 400
Multiply through by 9
9x² + 16x² = 3600
25x² = 3600
Divide both sides by 25
x² = 3600/25
x² = 144
Take the square root of both sides
x = √144
x = 12
Substitute x = 12 into equation 1
3/4 = x/y
3/4 = 12/y
Cross multiply
3y = 12 x 4
3y = 48
Divide both sides by 3
y = 48/3
y = 16

Answer: 2t + 10
Step-by-step explanation:
2t represents the number of triangles and 10 bookends the sides of the triangle(s). Notice in the picture each triangle base has a value of two, no matter how many triangles are grouped together. Now notice that no matter how many triangles are grouped together, 5 will always be on the left and right of the final picture.

hi please help me with this angles work for math class
Answer:
Angle A:60
Angle B:120
AngleD:60
Angle E:60
Angle F:120
Angle G:120
Angle H:60
Step-by-step explanation:
There are supplementary angles that add up to get 180 so 120+ __=180
60 is the missing Angle of A and D and since the lines are parallel and we also have vertical angles. The angles are going to be either 120 or 60

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 10 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively. Find the measures of the three angles
Answer:
1st ∡ = 15.5°
2nd ∡ = 77.25°
3rd ∡ = 87.25°
Step-by-step explanation:
1st ∡: x
2nd ∡: y
3rd ∡: z
Equations we can create from data given in problem:
y + z = 5x
z = 5x + 10
We have enough expressions to create an equation:
x + 5x + 5x + 10 = 180
11x = 170
x = 15.5
y = 5(15.5) = 77.25
z = y + 10 = 87.25
