Answer:
complementary angles
Step-by-step explanation:
∠1 and ∠2 form a right angle and are complementary, that is they sum to 90°
Well since its mental math u have to use your mind without working it out so 81-16=65
Answer:
ok so -3x3 is -9 and 8x7 is 56 so i think its -9/56
Step-by-step explanation:
Answer:
(a)€2048
(b)€4095
Step-by-step explanation:
So the amount of money we would save at nth month is
where n = 1, 2, 3, 4, ...
At the 12th month, meaning n = 12, we would save
= €2048 for that month
The total amount we would save in a year is
1 + 2 + 4 + 8 + 16 + ... + 2048
= €4095
Answer:
0.64π rad
Step-by-step explanation:
The formula for calculating the length of an arc is expressed as;
length of an arc = theta/360 * 2πr
r is the radius = 13 feet
arc length = 26feet
Substitute
26 = theta/360 * 2(3.14)(13)
26 = 81.64 theta/360
81.64 theta = 26 * 360
81.64 theta = 9360
theta = 9360/81.64
theta = 114.64
Hence the radian measure is 114.64/180 π = 0.64π rad
