Answer:

X=60

Step-by-step explanation:

The little square near 150 means- that angle is right, i.e 90.

Like you can see, x, 30 and 90 are on the the same straight line, so the some of them is 180.

30+90+x=180

120+x=180

x=60

Answer:

x = 60 degrees.

Step-by-step explanation:

The angle marked with a square indicates that it is 90 degrees. So the 'square' angle to the left of it is also 90 degrees, as they are on the same straight line, so their sum is 180 degrees.

Therefore x + 30 = 90

x = 60 degrees.

If QT is 9 and TP is 8 Find the length of the following:<br><br>RP<br>RT<br>RS

anyanavicka [17]

Answer:

i. RP = 17

ii. RT = 15

iii. RS = 30

Step-by-step explanation:

Given that; QT = 9 and TP = 8.

From the diagram, join R to P. Thus RP = QP (radius of the circle)

RP = QT + TP

= 9 + 8

RP = 17

Applying Pythagoras theorem to triangle TRP;

RT = $\sqrt{(RP)^{2} - (TP)^{2} }$

= $\sqrt{17^{2} - 8^{2} }$

= $\sqrt{225}$

= 15

∴ RT = 15

But, RT = TS = 15.

So that;

RS = 15 + 15

= 30

RS = 30

Therefore; RP = 17, RT = 15 and RS = 30.

Jimmy Walked a total of 6 miles last week. This week, he walks 2 miles each hour. If he walks 6 hours this week, how many miles

arlik [135]

Answer:

18 miles

Step-by-step explanation:

Find how many miles he walked this week by multiplying 2 by 6:

2(6)

= 12

Add this to 6, since he walked 6 miles last week:

12 + 6

= 18

So, in all, he will have walked 18 miles
