Your answer is A. he can get 19.37 songs because 25 divided by 1.29 is 19.37 (mark me as brainliest, this answer is 100% accurate)
Answer:
1)m<ABH=121°
2)m<GDF=59°
3)X=35
4)m<ABC=59°
5)m<EDA=59°
Step-by-step explanation:
1. You want to find X, so since the two expressions are Alternate Interoir Angles they equal each other
5x-54=3x+16
5x-3x-54=3x-3x+16
2x-54=16
2x-54+54=16+54
2x=70
2x/2=70/2
X=35
2. Now plug in X to each equation to test if it works
5(35)-54=3(35)+16
175-54=105+16
121=121
3. Now replace the two expressions with 121
4. Let's begin with <ABH. Since <ABH is verticle to 3x+16 they equal each other.
5. <GDF is right next to 5x-54 and they're on the same line meaning they equal 180°. So 180-121=59, this is also the reasoning with <EDA with 5x-54 and <ABC with 3x+16
NOTE: THIS ONLY IS TRUE IF LINE HC AND LINE GE ARE PARALLEL.
Central angle is twice an inscribed angle subtended by the same arc.
Therefore ∠CAB = 2∠CDB.
∠CAB = 45° → ∠CDB = 45° : 2 = 22.5°
Answer: C.
Answer:
the answer for the first part is 260
the equation is n+8
Step-by-step explanation:
all you need to do is take the starting number witch is 13 then you add 8 and then take that number and add 8 so thats why the equation is n+8 n equaling the starting number and 8 equaling to the reoccurring number.
Answer:
The sector given in the figure is a semi-circle because the degree measure of the chord is 180 degrees.
Area of semicircle = 0.5π
= 0.5π×4.5 = 6.75 sq. inches
