Answer:

x = 13

Step-by-step explanation:

Since the Two triangles are equivalent then angles B and D are isometric

i e 8x+16=120 then 8x=120-16 then 8x=104 then x=104÷8=13

Answer:

x=13°

Step-by-step explanation:

It is given that triangles ABC and EDC are similar, therefore angles ABC and EDC have the same measurement. Using this information, we can set up an equation.

$(8x+16)=120$

We can remove the parentheses, as they are unnecessary.

$8x+16=120$

We can now solve the equation for x. The first step is subtracting 16 from both sides.

$8x=104$

We can now divide both sides by 8, to isolate x. 104/8=13.

$x=13$

Lets not forget to add the degree symbol, as the problems is dealing with degrees.

x=13°

Two students, Matt and Billy , each calculated the volume of a spherical ball with a dime tee of 15 centimeters. Their work is s

Aleksandr-060686 [28]

Answer:

Matt ;

Used diameter of the ball instead of Radius

Step-by-step explanation:

The volume of a sphere is given as :

4/3πr³

Radius, r = diameter / 2

Given that, the diameter = 15 cm ; The Radius = 15 / 2 = 7.5 cm

Matt made an error in his calculation by failing to covert the value of the diameter given to Radius.

By dividing the diameter by 2 = 15 / 2 = 7.5, we obtain the Radius, which is what Billy did in her own calculation.
