Answer:
x = 21, m∠A = 23°, the measure of angle in the right = 67°
Step-by-step explanation:
The angles of a triangle sum up to 180°.
Right angles equals to 90°.
Thus, (2x - 19)° + (3x + 4)° + 90° = 180°
=> 5x + 75 = 180
=> 5x = 105
=> x = 21
m∠A=> 2(21) -19 = 23°
the measure of angle in the right=> 3(21) + 4 = 67°
Answer:
y=
+ 4
Step-by-step explanation:
Pick two points: (-6,-10) and (0,4)
Then solve for m (slope): I picked (0,4)

Then put in slope intercept form:
4=
+ b
4=b
Then put in final form:
y=
+ 4

Answer:

Step-by-step explanation:
To find the area of the inner circle, we need to find its radius. Here, we can write the radius as 4 - x. Now, we can use the formula
:
A =
* 
We can expand the square:
A = 
Thus, the polynomial is
.

105.0, 105%.
If one question is bonus, there are technically 20 questions on the test; 100/20 is 5, so each question is worth 5 points. 105 is 105% of 100.
