Answer:
The answer is x = 5.
Step-by-step explanation:
Given:
Δ ABC is an Isosceles triangle with AB = CA
m∠ ABC = ( 6x + 4 )°
m∠ BAC = 73°
m∠ BCA = ( 8y - 7 )°
To Find:
x = ?
Solution:
Properties of an Isosceles Triangle.
- Base angles or two angles are equal.
- Any two sides are equal.
Here , Δ ABC is an Isosceles triangle with AB = CA
∴ m∠ BAC = m∠ BCA
∴ m∠ BCA = ( 8y - 7 )°
= 8 × 10 - 7
m∠ BCA = 73 Which is same as ∠ CAB
Property of a Triangle is Sum of the measures of the angle of a triangle is 180°.
Substituting the values we get,
The answer is x = 5.
Using that formula we get:
so B is your answer :)
Answer:
In math, value can either refer to the result of a calculation or a variable or constant
<span>Step 1: Simplify both sides of the equation.
</span>1/2 (6−z) = <span>z
</span><span>
(1/2) (6) + (1/2) (-z) = z (distribute)
3 + -1/2z = z
-1/2z + 3 = z
</span><span>Step 2: Subtract z from both sides.
</span><span>
-1/2z + 3 - z = z - z
-3/2z + 3 = 0
</span><span>Step 3: Subtract 3 from both sides.
</span><span>
-3/2z + 3 - 3 = 0 - 3
-3/2z = -3
</span><span>Step 4: Multiply both sides by 2/(-3).
</span><span>
(2/-3) * (-3/2z) = (2/-3) * (-3)
z = 2
Answer: z = 2
I hope this helps you!:) Sorry it took me so long!
