Angles 1 and 2 are complementary, and angle 1=3x+3 and angle 2=10x-4, find the degree measure of each angle
tensa zangetsu [6.8K]

Answer:

The measure of the angles:

24°  and   66°

Step-by-step explanation:

Complementary angles sum 90°

then:

(3x + 3) + (10x-4) = 90

3x + 10x + 3 - 4 = 90

13x - 1 = 90

13x = 90+1

13x = 91

x = 91/13

x = 7°

then:

  • angle 1:

3x+3 = 3*7 + 3 = 21+3 = 24°

  • angle 2

10x - 4 = 10*7  - 4 = 70 - 4 = 66°

Check:

66° + 24° = 90°

The bases of a trapezoid are 16.8 yards and 6.9 yards. If the height is 2 yards, what is the area of the trapezoid?
Svet_ta [14]
Hello,
Here is the formula to find the area of the trapezoid:
A=1/2(b1+b2)×h
Where b1 represent big base
b2 represent small base
and h represent height
Now, we just need to replace the number to get the final answer:
A=1/2(16.8+6.9)×2
A=1/2(23.7)×2
A=23.7 square yards. As a result, the area of the trapezoid is 23.7 square yards. Hope it help!

Which one is cheaper and why
Shtirlitz [24]

Hey there! :)

Answer:

The bag is cheaper because one litre is roughly $1.00, compared to the carton which is $1.99 for one litre.

Step-by-step explanation:

Given:

Bag of 4 litre milk = $3.99

Carton of 1 litre milk = $1.99

Find the price per litre for a bag of milk:

\frac{3.99}{4} = \frac{x}{1}

Cross multiply:

3.99 = 4x

Divide both sides by 4:

3.99/4 = x.

x = 0.9975 ≈ $1.00

Bag of 1 litre milk ≈ $1.00

Carton of 1 litre milk = $1.99

$1.00 < $1.99

Therefore, the bag is cheaper.
