Answer:
18°, 72°, 90°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the parts of the ratio, 5 + 4 + 1 = 10 parts
divide to find the value of one part of the ratio
180° ÷ 10 = 18° ← value of 1 part of the ratio , thus
5 parts = 5 × 18° = 90°
4 parts = 4 × 18° = 72°
Thus the angles of the triangle are 18°, 72° and 90°
Answer:
Step-by-step explanation:
let the first angle be 5x
second be 4x
and third be 1x
as we know that by adding all the sides of triangle we get 180°
therefore ,
5x+4x+1x=180°
10x=180°
hence ,
x=18°
first angle - 18*5 = 90°
second angle - 18*4=72°
third angle - 18°

it is D

I know things dude. I got your back :-)
A Because if you do 156 x 20 it equals 3120. It’s A because the volume formula is Length x Width x height, And 156 and 20 were the only numbers given.
Standard form: Ax+By=C first put in slope-intercept form: slope = (0+5)/(6-3) = 5/3 pick point D: 0 = 5/3(6)+b -> b= -10 slope-intercept form: y=(5/3)x-10 multiply both sides by 3: 3y=5x-30 put in standard form:5x-3y=30
Subtract 6 from both sides, you get 1/3x=-14
Now multiply both sides by there, hence x=-42
