Answer:
number 2 is C and number 3 is D
Step-by-step explanation:
If the measure of angles ∠DAB = 51° and the value of x is 25. Then the measure of angle ∠CAB will be 25°.
<h3>What is an angle?</h3>
The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
If the measure of angles ∠DAB = 51°, ∠CAB = x, and ∠DAC = x + 1.
Then the measure of angle ∠CAB will be
We know
∠CAB + ∠CAD = ∠DAB
x + x + 1 = 51
2x = 50
x = 25
Then the measure of the angle ∠CAB will be
∠CAB = x
∠CAB = 25
∠CAB = 25°

I think its the second one, the answer does not have a definite and, and cannot be put into a ratio.
Answer:
14110
Step-by-step explanation:
Let x = number of pages ;
μ = 12200 ; σ = 820
Zscore = (x - μ) / s
Zscore = (x - 12200) / 820
Zcritical at 99% confidence, for a 1 - tail test is 2.33
Hence, Z at 99% = 2.33
Put Zscore = 2.33
Zscore = (x - 12200) / 820
2.33 = (x - 12200) / 820
2.33 * 820 = x - 12200
1910.6 = x - 12200
1910.6 + 12200 = x
x = 14110.6
x = 14111
The number of pages the manufacturer should advertise is 14,110
