Answer:

50°, 60°, 70°

Step-by-step explanation:

Sum the parts of the ratio, 5 + 6 + 7 = 18 parts

The 3 angles in a triangle sum to 180° , then

180° ÷ 18 = 10° ← value of 1 part of the ratio, then

5 parts = 5 × 10° = 50°

6 parts = 6 × 10° = 60°

7 parts = 7 × 10° = 70°

The angle measures of the triangle are 50° , 60° , 70°

Charles is 20% heavier than Edith. If Charles weighs 60kg, what is Edith's weight?

ddd [48]

Charles' weight = Edith's weight + 20% of Edith's weight

We'll use a variable to represent Edith's weight, x.

The decimal form of 20% is 0.2.

60 = x + 0.2x

60 = 1.2x

x = 50

Edith's weight is 50kg.

Hope this helps!

Use graph to answer the question

Vesna [10]

Answer: $36.86^{\circ}$

Step-by-step explanation:

Given

Coordinates of Point A is $(-3,-4)$ i.e. Point A is 3 units to the left and 4 units below x-axis

From figure, we can write

$\Rightarrow \tan \theta =\dfrac{3}{4}\\\\\Rightarrow \theta=\tan^{-1}\left(\dfrac{3}{4}\right)\\\\\Rightarrow \theta=36.86^{\circ}$

Dhanraj spent $204.20 purchasing volleyballs and basketballs.

Lemur [1.5K]

Answer:

Number of volleyballs bought = 8

Number of basketballs bought = 11

Step-by-step explanation:

Given that:

Total amount spent = $204.20

Let,

x be the number of volleyballs

y be the number of basketballs

According to given statement;

y = x+3 Eqn 1

8.20x+12.60y=204.20 Eqn 2

Putting value of y from Eqn 1 in Eqn 2

8.20x + 12.60(x+3) = 204.20

8.20x + 12.60x + 37.80 = 204.20

20.80x = 204.20 - 37.80

20.80x = 166.40

Dividing both sides by 20.80

$\frac{20.80x}{20.80}=\frac{166.40}{20.80}\\x=8$

Putting x=8 in Eqn 1

y = 8+3 = 11

Hence,

Number of volleyballs bought = 8

Number of basketballs bought = 11
