Answer:

A. 50

Step-by-step explanation:

Sum of interior angles of a triangle is always =180 °

Since this is a right triangle, therefore we know that one angle of the triangle measures 90°

Therefor sum of other two angles has to be = $180\°-90\°=90\°$

One angle measures = 40°

Therefore the missing angle $y=90\°-40\°=50\°$

$y=50\°$

For this case we propose a system of equations:

x: Variable representing the weight of large boxes

y: Variable that represents the weight of the small boxes

$x + y = 80\\55x + 70y = 4850$

We clear x from the first equation:

$x = 80-y$

We substitute in the second equation:

$55 (80-y) + 70y = 4850\\4400-55y + 70y = 4850\\15y = 450\\y = 30$

We look for the value of x:

$x = 80-30\\x = 50$

Large boxes weigh 50 pounds and small boxes weigh 30 pounds

A rectangle has a height of 3 cm and width of 5cm. A proportional rectangle has a height of 12cm. What would be the width?

Schach [20]

The ratio will be same

Let width be x

$\\ \sf\longmapsto \dfrac{3}{5}=\dfrac{12}{x}$

$\\ \sf\longmapsto 3x=5(12)$

$\\ \sf\longmapsto 3x=60$

$\\ \sf\longmapsto x=\dfrac{60}{3}$

$\\ \sf\longmapsto x=20cm$

Solve for X with steps

yarga [219]

Answer:

x= 17.78

Step-by-step explanation:

a^2 + b^2 = c^2

8^2 + b^2 = 18^2

b^2= 18^2-8^2

b^2 = 260

so you have to take square root i can't show the symbol of it so i am just do it

b= 16.12

then you use that for other tringle

same formula

24^2= x^2+16.12^2

x^2= 316.15

x= 17.78
