Answer:
Step-by-step explanation:
The Base Angle Theorem states that the base angles of the two equal legs of an isosceles triangle are equal. Since there are 180 degrees in a triangle, we have:
Answer:
<u>D. (a+b)⁶</u> is the right answer.
Step-by-step explanation:
[(a+b)³]²=(a+b)³*²=(a+b)⁶
The two given equations are:
<span>-14=-20y-7x and 10y+4=2x
In order to find x and y, we can do it by substitution or by elimination.
By Elimination.
</span><span>Multiply 10y+4=2x by 2
= 20y + 8 = 4x
Then add it to the second equation
</span>-20y - 7x = -14
20y - 4x = -8
---------------------
-11x = -22
x = 2
Then get y,
10y+4=2x
10y = 2x - 4
10y = 2(2) - 4
y = 0.
So the answer is x = 2, y = 0
Answer:
x = 29°
The angles are 137° , 116° , 96° , 44° and 147°
Step-by-step explanation:
The sum of the angles of the polygon is given as 540°. The angles are given as 5x – 8°, 4x°
, 96° , 44°, 5x + 2. Therefore, the value of x can be found as follows
5x – 8° + 4x° + 96° + 44° + 5x + 2° = 540°
collect like terms
5x + 4x + 5x - 8 + 96 + 44 + 2 = 540°
14x + 134 = 540°
14x = 540 - 134
14x = 406
divide both sides by 14
x = 406/14
x = 29°
Therefore, the angles are as follows
29 × 5 - 8 = 137°
29 × 4 = 116°
96°
44°
5 × 29 + 2 = 147°
