Answer:
40
Step-by-step explanation:
=m∠C+m∠A
=74°+26°
=100
a triangle always have a measure of 180°
180-100= 80
so 80 is left
the given is 2x so we need the half of the value so we can get the answer
remember 80 is only left
80÷2 is 40

Answer: 40
If an equation is given ,
X+2=4
=> X=4–2
=>X=2
We X's value as 2 .
Now another ,
X + Y = 5 , 2X + 5Y = 10
Now taking first equation
X = 5-Y ………………………..(1)
Now taking second equation
X= 10–5Y/2…………………(2)
Now,
2(5-Y) = 10–5Y
=> 10–2Y = 10–5Y
=> 2Y = 5Y
Y has no value here because this equation not correctly represented .
Hence ,
We conclude the value of X varies with equation .
