Answer:
35° and 55°
Step-by-step explanation:
The sum of the angles of a right rectagle is 180°, with a right angle of 90°.
The tell us that A = 2B-15, so:
180° = 90° + A + B
180° = 90° + 2B - 15 + B
180° - 90° + 15 = 2B + B
105° = 3B
B = 105°/3 = 35°
Now, let's find A:
A = 180° - 90° - 35° = 55°
Answer:
400 degrees
Step-by-step explanation:
Step 1 : To convert radians to degrees, multiply the given radian by 180/pi
7pi/3 x 180/pi
Step 2 : Cancel pi
7/3 x 180
= 420 degrees
Step 3 : Round it to nearest 100
Since 20 is closer to 400 than 500 therefore it will be rounded off to
400 degrees

Answer:
Both Jeff and Lori are wrong.
Step-by-step explanation:






-63 is the final answer
Area=height times base (for some prisms including cylinders)
vcylinder=hpir²
h=height
therefor pir²=base area
vcylinder=height times aeraofbase
given
h=9
v=324pi
324pi=9(basearea)
divide both sides by 9
36pi=areabase
the area of te base is 36pi square cm (put 36 in the blank since th pi is alredy there)
Answer:
Step-by-step explanation
Take the square root of both sides.
Add both sides by 5
