Answer:
Step-by-step explanation:
From what I understand, you are trying to solve for a.
So,
d=g+2ac
d-g=2ac
(d-g)/2c=a
So,
a = (d-g) / 2c

</span>To solve the equation by dividing both sides by 3<span>, or, which is the same thing, multiplying both sides by </span><span>( 1/3)</span><span>.

So answer: the multiplicative property of equality
20^2+21^2=29^2 can be used to determine if the triangle is a right triangle
Answer:
∠1=66⁰
∠2=24⁰
∠3=24⁰
∠4=90⁰
Step-by-step explanation:
∠2=∠ADB=24 (ΔADB is isosceles, so ∠ADB=∠ABD)
∠4 =90 (right angle)
∠3=24 (BD bisects ∠ABC, so ∠2=∠3)
∠1+∠2+90=180 (angles in triangle add to 180)
∠1=66
Step-by-step explanation:
Given A(1 , -3)
Reflection across the x -axis
= A'( 1 , 3)
Reflection across the y-axis
= A'( -1 , - 3)
Reflection across the y = x
= A' ( -3 , 1)
Reflection across the y = - x
=A'( 3 , - 1)
