Answer:
The measure of arc AC is 85°
Step-by-step explanation:
we know that
The inscribed angle measures half that of the arc comprising
so
m∠ABC=(1/2)[arc AC]
substitute
(4x-5.5)°=(1/2)[5x+25]°
(8x-11)°=(5x+25)°
8x-5x=25+11
3x=36
x=12°
Find the measure of arc AC
arc AC=(5x+25)°
arc AC=5(12)+25=85°
Answer:
The third angle of the triangle is 70°.
Step-by-step explanation:
The two angles of a triangle (say Δ ABC) are given to be 30° and 80°.
We have to find the third angle.
Let us assume that ∠ A = 30° and ∠ B = 80°, then we have to find ∠ C.
Now, we know that, ∠ A + ∠ B + ∠ C = 180° {Property of a triangle}
⇒ 30° + 80° + ∠ C = 180°
⇒ ∠ C = 180° - 30° - 80° = 70°
Therefore, the third angle of the triangle is 70°. (Answer)
So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.
a/b and c/d are rational numbers with a,b,c,d intergers
so with the same denominators ( equaling a+c over b) or different ones (equaling ab+cb over bd) they end up with the answers of
same denominator= b is not equal to 0
different denominators= d is not equal to 0
this may not make sense but i'm pretty sure i understood you right
