Every triangle’s inner angles’ addition equals to 180°
So if we find the x:
38°+x+2°+x=180°
40°+2x=180°
2x=180°-40°=140°
x=140°/2
x=70°
Now if we find the I hope this helped :)
Answer:
240km
Step-by-step explanation:
400km/5hrs = xkm/3hrs
cross multiply to get
1200=5x
divide both sides by 5
240=x
Rise / run dude.
First one would be 1 / 3 which is 0.33
So, the slope intercept equation would be y = 0.33x + 5 (5 is the Y intercept)
Second one is rise / run as well.
-5 / 4 = -1.25
So, the slope intercept equation would be y = -1.25x + -12
Answer:1. 12:6 equivalant ratio:24:12
Step-by-step explanation:
12:6 means twelve to 6 and to find a equivalant ratio means to find a number that 12 and 6 can equal so it would be 24:12 which i multiplied by 2.
The perimeter is 22cm therefore the remaining side is 22-8-5=9 cm. A right triangle follows the Pythagorean theorem which states that any side is equal to the square root of the sum of the squares of the other side or A=B2+C2. Using this we can get side AB and see if we can get it using the Pythagorean theorem. 52+92=10.30 cm<span>. therefore, triangle ABC is not a right-angled triangle</span>
