Each term is 0.19 more than its predecessor. You have
So, we can assume that the next terms will be
Answer:
∠A = 99°
Step-by-step explanation:
Complementary angles sum to 180°, thus
∠A + ∠B = 180 ← substitute values
2x - 23 + x + 20 = 180
3x - 3 = 180 ( add 3 to both sides )
3x = 183 ( divide both sides by 3 )
x = 61
Hence
∠A = 2x - 23 = (2 × 61) - 23 = 122 - 23 = 99°
Answer is B. 289
First find the area of the rectangle by multiplying Base x height. 17 x 13 = 221
Now to find the area of the huge triangle, you have to do (Base x height) / 2. So your height would be 8. Now your base would be the same as the length of the rectangle which is 17. (17 x 8) / 2 = 68
221 + 68 = 289
8 ( 20divided by 15=1.333 then times that by6)
And
60 (triple 15)
The distance of BF is 7.07
