Answer:
Measure of angle 3: C (46 degrees)
Step-by-step explanation:
As there is no attachment, I will assume the question is in reference to a triangle. Knowing that a triangle contains 3 angles the answer can be retrieved through simple steps:
m∠1 + m∠2 + m∠3 = 180 degrees, by Sum of Angles in Triangle Theorem, <em>thus;</em>
Through substitution + algebra:
134 + m∠3 = 180,
m∠3 = 46 degrees
Answer:
C is correct
Step-by-step explanation:
10x³+2x²+0x-11
+0x³+9x²+2x-2
=10x³+11x²+2x-13
We should find the original number, 7 of 1/10. We divide the known number for the numerator, than multiply for denominator.
7 : 1 = 7 * 10 = 70 <- answer
So 7 is 1/10 of 70
We can check our work:
1/10 of 70 = 7?
70 : 10 = 7*1 = 7
Use Pythagorean theorem:
9i-j = sqrt (9^2 - 1^2) = sqrt(81-1) = sqrt80
now divide both terms in V by that:
u = 9/sqrt(80)i - 1/sqrt(80)j
