Each triangle has a sum of angles that equal 180° so set each angle measure = 180

(x + 66) + (x + 86) + 50 = 180; add accordingly

2x + 202 = 180; subtract 202 from both sides

2x = -22; divide both sides by 2

x = -11

Plug in -11 for x to check

(-11 + 66) + (-11 + 86) + 50 = 180

55 + 75 + 50 = 180

180 = 180 so -11 is the correct value of x

 A farmer recently sold a large plot of land. The sale decreased his total acreage by 8​%. Let t be the original acreage. Find t
vlada-n [284]

Answer:

<u>D. 0.92t, is indeed a correct answer, but probably B or E are not correctly written. The second correct way is t - 0.08t.</u>

Step-by-step explanation:

If the farmer recently sold 8​% of the original acreage of his plot and t is the original acreage, therefore:

8% = 0.08

Thence, the expressions to describe two ways to find the new acreage are:

t - 0.08t

t - 0.08t = 0.92t

<u>D. 0.92t, is indeed a correct answer, but probably B or E are not correctly written. The second correct way is t - 0.08t.</u>

BC is tangent to circle A at B and to circle D at C. AB=9, BC=26, and DC=8. Find AD to the nearest tenth.
Ksju [112]
There are two circles with center  A and D. The tangent line touches both point B and C. The given measurements are enough to solve for the missing value and the solution is shown below:
AB=9
BC=26
DC=8
Solve for the measurement of AC which the hypotenuse of legs AB and BC by Pythagorean theorem:
c²=a²+b²
c²=9²+26²
c=AC=27.51
Solve for angle of A 
sin A=26/27.51
A=70.93° 
Finally, we solve for the length of AD using SOH
sin 70.93°=AD/27.51
AD=26
The answer is 26.

Alan wants to buy a bike that has a regular price of $169. This week the bike is on sale at a 35% discount.
sammy [17]

Answer:

Alan can buy the bike for $109.85

Step-by-step explanation:

Start with 100% and subtract the 35% discount.  This results in 65%.  The bike sells for 65% of $169, which is calculated as follows:

0.65($169) = $109.85

Alan can buy the bike for $109.85 under the terms of this sale.
