I think it’s C sorry if I’m wrong
Answer:
in this case you can use protector also but
there is another way
Step-by-step explanation:
as we know sum of a triangle is 180 degree
so let's D= 2x,x
35+x+2x=180
3x+35=180
3x=180-35
3x=145
x=145÷3
x =46.06
Answer:
65/9
Step-by-step explanation:
3 1/3=(3*3+1)/3=10/3
2 1/6=(2*6+1)/6=13/6
10/3*13/6=130/18=65/9
4 because 2.5+2.5=5 and another 2.5+2.5=5
now 5+5=10
That would be true because the adjacent side to B is 4 and the hypotenuse is 5 and the formula for cos b is adjacent/hypotenuse
Hope this helps!
