Answer:
7 x 9 = 63, 63 divided by 2 = 31.5,
31.5 x 4 = 126
9 x 9 = 81
Add given areas:
126 + 81 = 207 in2 is your answer
Answer:
its 12
Step-by-step explanation:
LCM of 3,4 and 6 is 12
Answer:
Step-by-step explanation:
Keep in mind that the tangent function is negative in Quadrants II and IV.
Of the three possible answers, the 2nd is invalid because the tangent is positive in Q III.
If the reference angle were in Quadrant II and had the value 30° (second possible answer), then the opposite side would be +1, the adjacent side -√3 and the hypotenuse 2. Based on this, the tangent of theta would be opp / adj, or +1 / (-√3) or -√3/3. This is correct.
Answer:
![x=17.5^o](https://tex.z-dn.net/?f=x%3D17.5%5Eo)
Step-by-step explanation:
<u><em>The question is </em></u>
Find the value of x
we know that
If sin(A)=cos(B)
then
angle A and angle B are complementary angles
so
![A+B=90^o](https://tex.z-dn.net/?f=A%2BB%3D90%5Eo)
In this problem
![sin(x)=cos(3x+20)](https://tex.z-dn.net/?f=sin%28x%29%3Dcos%283x%2B20%29)
so
![x^o+(3x+20)^o=90^o](https://tex.z-dn.net/?f=x%5Eo%2B%283x%2B20%29%5Eo%3D90%5Eo)
solve for
![4x+20=90](https://tex.z-dn.net/?f=4x%2B20%3D90)
![4x=90-20](https://tex.z-dn.net/?f=4x%3D90-20)
![4x=70](https://tex.z-dn.net/?f=4x%3D70)
![x=17.5^o](https://tex.z-dn.net/?f=x%3D17.5%5Eo)
B) a=2/3, b=0, c=3 would be the correct answer
