Angle DGH is 137/2 = 68.5, and angle HJG is 89. So we can find angle EHG as follows:
180 - (68.5 + 89)
= 180 - 157.5
= 22.5
Arc EG is twice 22.5, which is 45 degrees
Arc DE is 360 - (137 + 61 + 45), because the number of degrees in a circle is 360. We simplify as follows:
Arc DE = 117 degrees.

yulyashka [42]

Answer:

$m=4$ or $m=\frac{4}{1}$

Step-by-step explanation:

To find slope we use the slope formula

$m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

Two points on the line we can classify are (3,4) and (4,8)

Need help asap The answer is 100 or 126

Serga [27]

Answer:

The surface area of the cone is 126π cm².

Step-by-step explanation:

The surface area of a cone can be found using this formula:

$\text{SA} = \pi r ^2+\pi r l$
where r = radius and l = slant height

In this problem, we are told that the cone has a radius of 9 cm and a slant height of 5 cm.

Substitute these values into the formula for the surface area of a cone.

$\text{SA}= \pi (9)^2+ \pi(9)(5)\\$
$\text{SA}= \pi (81)+ \pi(45)$
$\text{SA}= 126 \pi$

The surface area of the right cone is 126 π cm².
