15. 70° because a right angle is 90° and we have the angle of ADB which is 20°. So 90°-20°=70°.

16. 70° because angle PSQ is 60° and angle QSR is 10°. So 60°+10°=70°.

17. 55° because it says it in the explanation. I assume this is a typo and they meant to ask the measurement of ADC and in that case it would be 130° because angle ADB is 75° and angle BDC is 55°. 75°+55°=130°.

18. 40° because angle PSQ is a right angle which means it's 90°. So 130°-90°=40°.

19. 140° because angle ADB is 120° and angle BDC is 20° so 120°+20°=140°.

20. 125° because again it's in the explanation. But if it's a typo and they meant what is the measurement of PSQ then it is 50° because PSR is 125° and QSR is 75° so 125°-75°=50°.

Hope this helps! :)

Answer:

lower limit is n=1

upper limit is n=18

n=1 to 18∑(7n-4)

Number of beads = 1125

Step-by-step explanation:

Given series is 3+10+17+24.....

we find the formula to find nth term(explicit formula)

first term (a1) = 3

common difference (d)= 7

a_n = a_1+(n-1)d

a_n = 3+(n-1)7

a_n = 3+7n-7

a_n =7n-4

total of 18 rows

So we find sum for n =1  to 18

lower limit is n=1

upper limit is n=18

n=1 to 18∑(7n-4)

(b) to find total number of beads we apply sum formula

s_n = \frac{n}{2}(2a+(n-1)d)

n=18, a=3, d= 7

s = \frac{18}{2}(2(3)+(18-1)7)

S= 9(125)=1125

Number of beads = 1125

Area for rectangle in the coordinate plane. IXL Geometry help pls !
Sidana [21]

Answer:

Step-by-step explanation:

The co-ordinates of the rectangle are:

A (8, 6)

B (-4, -10)

C (-8, -7)

D (4, 9)

The Area of Rectangle is Given by: <em>length x breadth </em>= AB x BC

Lengths of AB and BC can be found by distance formula

<em>length</em>(AB) = \sqrt{(x_{2} - x_{1} )^{2} + (y_{2} - y_{1} )^{2}} = \sqrt{(-4-8)^{2} + (-10-6)^{2}} = 20

Similarly,

<em>length</em>(BC) = 5

Area of Rectangle = AB x BC = 20 x 5 = 100 square units
