Answer:

4.50 or 4.5. The only reason you got it wrong was because you didn't round to the nearest hundredth. 4.499 rounds up to 4.50

Step-by-step explanation:

Hopefully you know what the sine and cosine functions are...

So you gotta use the sine function for this equation since you are given the hypotenuse and B.

$sine(40)=\frac{x}{7}$

We put the degree measure next to sine because there can only be one unknown

So we can solve from here by multiplying both sides by 7

$(7)sine(40)=x$

Now put your calculator in the degree mode and insert this equation into it.

You get 4.499 rounded to the nearest hundredth is 4.50

Answer:

m(arc ZWY) = 305°

Step-by-step explanation:

8). Formula for the angle formed outside the circle by the intersection of two tangents or two secants is,

Angle formed by two tangents = $\frac{1}{2}(\text{Difference of intercepted arcs})$

= $\frac{1}{2}(220-140)$

= $\frac{1}{2}(80)$

= 40°

9). Following the same rule as above,

Angle formed between two tangents = $\frac{1}{2}(\text{Difference of intercepted arcs})$

125 = $\frac{1}{2}[m(\text{major arc})-m(\text{minor arc})]$

250 = $[m(\text{arc ZWY})-m(\text{arc ZY})]$

250 = m(arc ZWY) - 55

m(arc ZWY) = 305°

Therefore, measure of arc ZWY = 305° will be the answer.

10). m(arc BAC) = $\frac{1}{2}([m(\text{arc BDC})-m(\text{arc BC})])$

= $\frac{1}{2}(254-106)$

= $\frac{148}{2}$

= 74°

Please help me with this question!!

quester [9]

Answer:

Step-by-step explanation:

a1 = 6

a2 = 10

a3 = 14

The next member of the sequence is 4 more than the current sequence. Therefore d = 4

a1 = 6

d = 4

n = 13

an = a1 + (n - 1)*d

an = 6 + (n - 1)*4

a_13 = 6 + 12*4

a_13 = 6 + 48

a_13 = 54
