Answer:
48°
Step-by-step explanation:
ΔACB is isosceles, so angles A and B have the same measure. The measure of angle C in that triangle is ...
∠C = 180° -2(69°) = 42°
Angle C in ΔCDE has the same measure. Angle D is the complement of that:
∠D = 90° -42° = 48°
_____
The relations we used are ...
- the sum of angles in a triangle is 180°
- base angles of an isosceles triangle are congruent
- vertical angles are congruent
- acute angles in a right triangle are complementary
<span>–6(x – 2y) when x = –3 and y = –5
so
</span><span>–6(x – 2y)
= </span><span>–6(-3 – 2(-5))
= -6(-3 + 10)
= -6(7)
= -42
answer
</span><span>A. -42</span>
It is 36
Bcuz 3X6=18
And 18X2=36
Hope i helped ^_^
Answer:
12 ( B )
Step-by-step explanation:
mode means the number that appears the most often
in that case the mode is 12 ( B )
We know |x| ≥ 0 for all real numbers. Therefore your answer is x ∈ ∅ (no solution).
