Answer:
Let A and B be the enclosed acute angles
Since the right angle plus A and B = 180
90 + A + B = 180
A + B = 90
(The solution shown omits the right angle)
If A or B = 42 then the other angle = 48 deg
Answer:
Answer is 2 root under 20
Answer:
False.
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
to prove if NP is tangent to MN
we could prove if NPM is a right triangle
By pythagorean theorem
a^2+b^2=c^2
where a=MN=33
b=NP=180
c=MP=MQ+QP=152+33=185
so
33^2+180^2=185^2
but
1089+32400 is not equal to 34225
33489 is different from 34225
For "less than or equal to" you can use <=
For "greater than or equal to" you can use >=
√(15(x−1)) / √(2x^2)
Value under square root must be ≥ 0
Value in denominator not = 0
15(x−1) ≥ 0
x−1 ≥ 0
x ≥ 1
2x^2 > 0
x^2 > 0
x ≠ 0
Combining both inequalities, we get:
x ≥ 1
