Answer:
x = 50°
Step-by-step explanation:
Sum of Angles in a Triangle: 180°
All angles in a triangle must add up to 180°.
Step 1: Set up equation
x + 70° + 60° = 180°
Step 2: Solve for x
Combine like terms: x + 130° = 180°Subtract 130 on both sides: x = 50°Answer:
50°
Step-by-step explanation:
Step 1:
x + 70° + 60° = 180° Sum of a Δ
Step 2:
x + 130° = 180° Combine Like Terms
Step 3:
x = 180° - 130° Subtract 130° on both sides
Answer:
x = 50°

Answers
Answer:
Row 3 should show 7 feet is equivalent to 84 inches.
Step-by-step explanation:
First divide 36 and 3 to find the constant proportion. Which you get 12
Now multiply 12 x 3 , 12 x 6, 12 x 7, and 12 x 9
You should be able to find the incorrect answer which is row 3
12 x 7 actually equals 84 not 94

How do you know? Explain your steps.
Answers
to know this, you have to evaluate each equation and compare your answers.
10^3 = 1,000
23•1,000 = 23,000
10^4 = 10,000
11•10,000 = 110,000

[tex]11\times 10^4[/tex] is the greater number among the given.
The given numbers are 23×10³ and [tex]11\times 10^4[/tex].
We need to identify which is the greater number among the given.
What is scientific notation?The scientific notation helps us to represent the numbers that are very huge or very tiny in a form of multiplication of single-digit numbers and 10 raised to the power of the respective exponent. The exponent is positive if the number is very large and it is negative if the number is very small.
Now, 23×10³=23×1000=23000 and [tex]11\times 10^4[/tex]=11×10000=110000
Therefore, [tex]11\times 10^4[/tex] is the greater number among the given.
