Answer:
The area of the traingle AOB is 30 (Rounded up result)
Step-by-step explanation:
7.8 cm and 10 cm.
10/2= 5 cm
Then Reversed Pitagora's Formula:
Square root of the calc "(7.8^2)-(5^2)" = 60,84 - 25 = 35,84
Then Square root of 35, 84 is 5,98.
5.98 is the height of the triangle AOB
With the height we can calculate the area
We use the formula (B*H)/2
So is (10*5,98)/2, that makes 29,9
Just round up to 30 and that's the area.

A quadrilateral has two angles that measure 10° and 70°. The other two angles are in a ratio of 3:11. What are the measures of those two angles?
Answers
Answer:
The measures of those two angles are 60° and 220°
Step-by-step explanation:
The sum of the measures of the angles of any quadrilateral is 360°Let us solve the question
∵ A quadrilateral has two angles that measure 10° and 70°
→ By using the rule above, subtract their measure from 360
∴ The sum of the other two angles = 360° - 10° - 70°
∴ The sum of the other two angles = 280°
∵ The other two angles are in a ratio of 3: 11
→ Find the sum of the parts of the ratio
∵ The sum of the parts of the ratio = 3 + 11 = 14
∵ The sum of the measures of these 2 angles is 280°
→ By using the ratio method
→ m∠1 : m∠2 : their sum
→ 3 : 11 : 14
→ x : y : 280°
→ By using cross multiplication
∵ x × 14 = 3 × 280
∴ 14x = 840
→ Divide both sides by 14
∴ x = 60
∴ m∠1 = 60°
∵ y x 14 = 11 x 280
∴ 14y = 3080
→ Divide both sides by 14
∴ y = 220
∴ m∠2 = 220°
∴ The measures of those two angles are 60° and 220°

Solve it for me, and tell me how to do it EXPLANATION NEEDED

But, when solving this equation you are trying to find the value of x. To do that you have to get rid of the 3.
You would either add or subtract the 3 on both sides.
When the three is gone you should have somthing like
x = 5
- 3
Which you would move on to subtract the 5-3 and get 2.
x= 2

The chart below shows how many cups of lemonade Marcia sold each hour she had her lemonade stand set up. To make 10 cups of lemonade, Marcia has to squeeze 3 lemons. How many lemons did Marcia use in the first 4 hours?
Answers
Answer:
[tex]123\frac{1}{3}\ cups[/tex]
Step-by-step explanation:
Given
[tex]10\ cups = 3\ lemons[/tex]
See attachment for chart
Required:
Lemons used in first 4 hours
First, we calculate the number of lemon sold in the first 4 hours.
[tex]Lemon = 6 + 5 + 11 + 15[/tex]
[tex]Lemon= 37[/tex]
Represent the number of cups of lemonades needed with x
So, we have:
[tex]x = 37\ lemons[/tex]
and
[tex]10\ cups = 3\ lemons[/tex]
Cross Multiply:
[tex]x * 3 = 10 * 37[/tex]
[tex]3x = 370[/tex]
Make x the subject
[tex]\frac{3x}{3} = \frac{370}{3}[/tex]
[tex]x = \frac{370}{3}[/tex]
[tex]x = 123\frac{1}{3}[/tex] cups

Answer:
C. 6 units
Step-by-step explanation:
The second triangle is a translation of the first. A translation is a figure the slides up, down, left, right, etc. Essentially, it changes it's location.
A translation does not change it's size!
Therefore, it would still be the same length as AC, which was 6 units.

Answers
Answer:
30°
Step-by-step explanation:
Let the measure of the missing angle be x°
Therefore, by interior angle sum postulate of a triangle:
x + 60° + 90° = 180°
x + 150° = 180°
x = 180° - 150°
x = 30°
Thus the measure of the missing angle is 30°.
