I'd like to assume that the triangle is a right triangle and you solve for x so...
133 + c = 180 (supplementary property to find one angle of triangle)
c = 47
x = 180 - 90 - 47 (int. angles of triangle = 180)
= 90 - 47
= 43
Therefore, x is 43 degrees
Answer:
26
Step-by-step explanation:
8+10+8=26
The first two negatives cancel out and you're left with positive 4. Now go inside the square root and do the exponent. -4*-4 = 16. Then do the -4*3*1 = -12. Do 16-12 = 4. now the square root of 4 = 2. at the dominator is 2*3 = 6. right now they problem should look like 4+- 2/ 6. from there you split the problem in two. so you have 4+2/6 & 4-2/6 then you solve both problems.
6/6 2/6
1 1/3
1 & 1/3 are your answers. I hope this helped!
