Answer:
A) This is correct. The angles of <em>AEB </em>are the angles of <em>DEC. </em>This means that this is true.
B) This is incorrect. This triangle is NOT an isosceles triangle. The angles of an isosceles triangle are supposed to be about 36° for the top angle, and 72° for the other two angles. (At least this is what I was told)
Hope this helps :)
-wait. .___. they both might be true.
According to G oogle: "All the three angles situated within the isosceles triangle are acute, which signifies that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°, which means we can find out the third angle of a triangle if the two angles of an isosceles triangle are known."
Hey There!
80+70 is 150
180
-150
is 30 so 30 must be your answer
Hope This Helps!!!
-3 x -26 = 78
meaning the answer is D.
The reason the answer is D, is because two negatives when multiplied or divided become positive. Only when multiplied or divided does this occur.
Answer:
x=-119
Step-by-step explanation:
23-x=142
-23 -23
-x=119
switch the signs
x=-119
-7(k+9)=9(k-5)-14k
-7k-63=(9k-45)-14k
-7k-63=-5k-45
-7k=-5k+18
-2k=18
k=-9
