Answer:
Part a) 
Part b) IHG is a semicircle and GJI is a semicircle
Part c) HIJ is a major arc and HIJG is a major arc
Part d) 
Part e) 
Step-by-step explanation:
Part a) Give an inscribed angle
we know that
The inscribed angle measures half that of the arc comprising
so
in this problem m<HIG is an inscribed angle
----> by central angle
substitute
Part b) Give a semicircle
we know that
The diameter divide the circle into two semicircles
so
GI is a diameter
therefore
IHG is a semicircle
GJI is a semicircle
Part c) Give a major arc
we know that
The measure of a major arc is greater than 180 degrees
therefore
HIJ is a major arc
HIJG is a major arc
Part d) Measure of arc GH
we know that
----> by central angle
so
Part e) Measure of arc GJI
we know that
----> the arc represent a semicircle
Answer:
perfect square roots is when you have two of the same number that if you multiply them you get it. Example: the square root of 36 is six, because six times another six is 36- so 36 is a perfect square root number. 20 doesn't have a perfect square root because there are no two of the same numbers that will get you 20.
Hello!
To solve this, find the equal to each equation.
16 / 4 + 12. ====> 4 + 12.
4 + 12 ====> 16.
4 + 24 / 2. ====> 4 + 12.
4 + 12 ====>.
16 = 16.
Hope this helps! ☺♥
Answer:
∠DAB = 80°
∠BAC = 105°
Step-by-step explanation:
You are given ...
∠DAC = 25° = (x -20)°
Adding 20°, we have ...
x° = 45°
Then the measures of the other angles are ...
∠DAB = (2x -10)° = 2(45°) -10°
∠DAB = 80°
and
∠BAC = ∠DAB +∠DAC = 80° +25°
∠BAC = 105°
