Answer:

angle 1: 80 degrees

angle 2: 112 degrees

angle 3: 131 degrees

angle 4: 80 degrees

angle 5: 37 degrees

Step-by-step explanation:

start out with angle three subtract 49 from 180 ( a straight line must be 180 degrees) and u get 131. then add 63 and 49 up and subtract from 180. you get 68. angle 2 would be 180 - 68 and you get 112. once you know angle 2, you add up 31 and angle two (112 degrees) and subtract from 180, which leaves you with 37 degrees (angle 5). Add up angle 5 (37 degrees) and 63 degrees and subtract from 180, you get 80 degrees (angle 4). and opposite nagles equal each other so angle one is also 80 degrees.

What is the ratio of the circumferences for two circles with areas 6π m2 and 150π m2?

hichkok12 [17]

$\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{Area_1}{Area_2}\bigg)
$

$\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{6 \pi }{150 \pi }\bigg)
$

$\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{1 }{25}\bigg)
$

$\dfrac{Length_1}{Length_2} = \sqrt{ \dfrac{1}{25} } 
$

$\dfrac{Length_1}{Length_2} = \dfrac{1}{5}$

-------------------------------------------------------------
Answer: The ratio of the two circles = 1 :5

Angle Side Relationship 1/5 Will mark brainlist to whoever answers first

tresset_1 [31]

Answer:

m<A > m m<C

Step-by-step explanation:

In triangles, the measure of angles is proportional with the side length's they see,

The angle with the biggest the biggest measure sees the biggest side length

in triangle ABC the side lengths are given as

BC = 14, CA = 13 and AB = 5

from this, we can conclude:

m<A > m m<C

PLEASE HELP I HAVE NO CLUE WHAT IM DOING. Parents finna ground me if I don't do this tonight.

umka21 [38]

Answer:

First find x and y at given parameters:

x = (v₀cosθ)t = (123 cos60°)t = 61.5t
y = h + (v₀sinθ)t - 16t² = 0 + (123 sin 60°)t - 16t² = 106.52t - 16t²

Maximum height is at vertex. Time is:

t = -106.52/-32 = 3.3 seconds

Maximum height is:

y = 106.52*3.3 - 16(3.3)² = 177.3 ft

Horizontal distance:

x = 61.5*3.3 = 203 feet

Time to hit the ground:

106.52t - 16t² = 0
16t = 106.52 (t = 0 is discounted)
t = 106.52/16
t = 6.7 seconds

angle x= 77° because base angles on an isosceles triangle are the same.

hope that helped^^
