3. The total angle is 115, and one chunk of it is 90. Subtracting the two, gives us 25°, which should be the other measure, as m∠ABE and m∠EBC should add up to m∠ABC.

4. Same thing as before. m∠DGJ and m∠JGK should add up to m∠DGK.

Therefore, m∠DGJ is 70 - 40 = 30°.

5. When two 45° angles are put together, it will be 90°, or as it is usually called, a right angle.

Which expression is equivalent to t2 – 36?

defon

Answer:

(t + 6)(t - 6)

Step-by-step explanation:

(t - 6)(t + 6)

(t . t) + (t . (6) + ((-6) . t) + ((-6) . 6)

= t² - 6t + 6t - 36

= t² - 36

so,

t² - 36 = (t + 6)(t - 6)

Ben was walking in Manhattan at a constant speed. He went along 5th avenue from 4th to 98th street. At 3:00 he was on 15th stree

Answer: The starting time is 2:27 and finishing time is 7:09.

Step-by-step explanation: It is given that Ben started from 4th street and he finished at 98th street.

Also, at 3:00, he was on 15th street and at 4:30, he was on 45th street.

That is, time taken to cover (45-15), i.e., 30 streets is 90 minutes, so the time taken to cover 1 street is 3 minutes.

Therefore, Ben covers distance from one street to second in 3 minutes. Since he started from 4th street, and there are 11 streets to cover between 4 and 15, so Ben's starting time was (3:00 - 3×11 min) = 2:27.

And his finishing time was (4:30 + 3×53 min) = 7:09.

Again, the equation that tells us on what street 'N' he was after time 'T' of his starting can be written as

$N=4+\dfrac{T}{3.}$
