8) A) acute 9) C) acute 10) D) right 11) B) acute
12) A) straight 13) A) acute 14) D) right 15) C) ∠L
16) B) ∠HIG 17) B) ∠DEC 18) B) ∠K 19) C) ∠G
20) C) ∠KLJ
We know that ,
1. when 0° < θ < 90°, θ is acute.
2. when θ = 90° θ is right
3. when 90° < θ < 180°, θ is obtuse
4. when θ = 180° θ is straight

Answer: C. If two lines are parallel, then the alternate interior angles formed are congruent.</h3>
This is through the alternate interior angles theorem. Angles Q and T pair up as one alternate interior set of angles that are the same measure. The same thing applies to angles X and R.
The identical arrow markers on segments XQ and TR show that those segments are parallel. Segment TQ is one transversal cut (forming alternate interior angles Q and T). Segment XR is the other transversal cut (forming alternate interior angles X and R).
We could say "angle XRT" or "angle TRX" instead of "angle R", though its ideal to use shortcuts whenever possible. The same applies for the other angles as well.
Answer:
30/42 = 10/14 = 5/7
Step-by-step explanation:
The expression that is equivalent to the given expression where the expression is given as (18)2⋅(19)2 is (18 * 19)^2
<h3>How to determine which expression is equivalent to the given
expression? </h3>
The expression is given as
(18)2⋅(19)2
Rewrite the above expression properly
So, we have
(18)^2 * (19)^2
The factors in the above expression have the same exponent.
So, the expression can be rewritten as
(18 * 19)^2
Hence, the expression that is equivalent to the given expression where the expression is given as (18)2⋅(19)2 is (18 * 19)^2
