Answer:
The answer to your question is 6.- B 7.- D
Step-by-step explanation:
Data
Parallelogram ACFG
6.-
m∠GAC = 112°
m∠ACF = ?
Process
These angles are supplementary, they measure the same.
∠GAC + ∠ACF = 180
-Substitution
112 + ∠ACF = 180°
-Solve for ∠ACF
∠ACF = 180° - 112°
-Result
∠ACF = 68°
7.-
m∠AGF = 2a + 10
m∠ACF = a + 20
The angles ∠GAC and ACF are equal, they measure the same.
∠GAC = ∠ACF
-Substitution
a + 20 = 2a + 10
-Solve for a
a - 2a = 10 - 20
-Result
-a = -10
a = 10
-Find ∠AGF
∠AGF = 2(10) + 10
20 + 10
= 30°
Answer:
2.3 × 10^-7
Step-by-step explanation:
First, create an equation with the initial decimal being the coefficient multiplied by 10 to the power of 0.
(For example, let’s create the starting scientific notation equation for the decimal 475,000).
475,000 = 475,000 × 10^0
-------------------------------------------------------------------------------------------------------------
Now that we have an equation, the second step is to move the decimal point in the coefficient until there is 1 significant digit to the left of the decimal point. For each space the decimal point is moved to the left, increase the exponent by 1.
(Continuing the example above, move the decimal point to the left and increment the exponent.).
475,000 = 475,000.0 × 10^0
475,000 = 47,500.0 × 10^1
475,000 = 4,750.0 × 10^2
475,000 = 475.0 × 10^3
475,000 = 47.5 × 10^4
475,000 = 4.75 × 10^5
