Answer:
1. Angles 2, 3 and angles 1,3 are complementary angles(Given)
2. To prove :
Since Angles 2, 3 and angles 1,3 are complementary.
When angles are complementary, then the sum of the measures of angles is 90 degrees.
So, and (Definition of Complementary angles)
3. (Substitution)
4. (Subtraction property of equality)
Step-by-step explanation:
It is 7.5kg I’m not sure if your trying to find the kg
<span>3x+5y=4...(1)
2x-y=-7...(2)
by(2) : y = 2x+7
subsct in (1) :
3x +5(2x+7) = 4
13x = - 31
x = -31/13
y = 2(-31/13)+7 = 29/13</span>
(2/3) / (3/4) =
2/3 * 4/3 =
8/9 <==
