Hello!
The interior angles of every triangle add to equal 180 degrees. With that, you can add all angle expressions and set them to equal 180 to find x:
180 = 2x + 50 + x + 46 + 3x
180 = 6x + 96
84 = 6x
14 = x
Now, substitute 14 for x in each expression to find the value of each angle:
2x + 50 => 2(14) + 50 => 28 + 50 => 78
x + 46 => 14 + 46 => 60
3x => 3(14) => 42
Let's check our work:
180 ? 78 + 60 + 42
180 = 180 <--True
Angle A = 42 degrees
Angle B = 78 degrees
Angle C = 60 degrees
Hope this helps!
Answer:
a=36,b=144
Step-by-step explanation:lets take a as 1x
and b as 4x
their sum will be 180°(linear pair)
1x+4x=180
5x=180
x=180/5
x=36
so a=1×x=1×36=36
b=4×36=144
hope this helps
pls mark me b rainliest

Answer:
George is 1.49 m tall.
Hope it helps!
Step-by-step explanation:
Katie's height = 1.58 m
George is 9 cm shorter
Convert this to m..
9cm = 9/100 = 0.09 m
So his height is ,
1.58 - 0.09
= 1.49 metres
