Angles in a traingle always add up to 180°. in an isosceles triangle, 2 of the angles are the same, so if one angle is 100°, the other 2 must be 180-100=80/2=40
the other 2 angles would be 40° and 40°
Answer:
x=18
Step-by-step explanation:
S=(n-2)180
S=(5-2)180
S=3x180
S=540
540=(9x-6)+(3x+23)+95+((7x-4)+90
540=19x+198
540-198=19x
342=19x
342/19=x
x=18
Answer:
84 feet
Step-by-step explanation:
Let the feet be A
1 foot = 0.33 yard
A feet = 28 yards
Cross multiply
A x 0.33 = 28 x 1
Divide both sides by 0.33
A x 0.33/0.33 = 28/0.33
A = 84.84
A = 84 feet
Therefore, there are 84 feet in 28 yards
To find out the answer, let's factor out -42 (as if it's a positive number).
42: 1 x 42, 2 x 21, 3 x 14, 6 x 7.
With these given factors and due to the product being negative, we will go on and off with them being negative to find which sum up to 11.
Let's try 1 and 42.
-1 + 42 = 41
-42 + 1 = -41.
1 x 41 is not our answer.
Let's try 2 and 21.
2 - 21 = -19
-2 + 21 = 19
2 x 21 is not our answer.
Let's try 3 and 14.
-3 + 14 = 11
3 - 14 = -11.
Your answer is:
-3 and 14 sum up to 11 and make a product of -42.
-3 and 14 are your numbers.
I hope this helps!
The answer is B 1
Because the line intercepts the y axis when y = 1
