Answer:

∠A = 70°, ∠B = 50°, and ∠C = 60°.

Step-by-step explanation:

In a triangle ΔABC, ∠A + ∠B + ∠C = 180° ......... (1), we know from the property of triangle.

Now, the sum of ∠C and the exterior angle adjacent to ∠C is 180°.

If the exterior angle adjacent to ∠C is 120°, then ∠C = 180° - 120° = 60°.

Now, from equation (1), ∠A + ∠B = 180° - ∠C = 180° - 60° = 120° ......... (2)

Now, given that ∠A = 2x and ∠B = x + 15.

Hence, from equation (2), we have, 2x + x + 15 = 120

⇒ 3x = 105

⇒ x = 35.

Therefore, ∠A = 2x = 2 × 35 = 70°

∠B = x + 15 = 35 + 15 = 50°

and ∠C = 60° (Answer)

Please help with questions 1d and e
Aleksandr-060686 [28]

(d) \frac{75}{2}, \frac{75}{4}, \frac{75}{8}

(e) 68, 82, 96

(d) note that the terms have a common ratio ( r )

r = \frac{300}{600} = \frac{150}{300} = \frac{1}{2}

to obtain any term in the sequence, multiply the previous term by \frac{1}{2}

75 × \frac{1}{2} = \frac{75}{2}

\frac{75}{2}× \frac{1}{2} = \frac{75}{4}

\frac{75}{4} × \frac{1}{2} = \frac{75}{8}

(e) note that the terms have a common difference (d )

d = 26 - 12 = 40 - 26 = 54 - 40 = 14

to obtain any term in the sequence, add 14 to the previous term

54 + 14 = 68

68 + 14 = 82

82 + 14 = 96

Change 270.50° to degrees mins and seconds
Allushta [10]
The whole unit ( numbers to the left of the decimal will remain as the degrees:

270 will remain as degrees

now multiply the decimal by 60:

0.50 * 60 = 30  ( this becomes the minutes) if the answer had a decimal, you would multiply that decimal by 60 for the seconds, but since multiplying 0.50 by 60 was a whole number there are zero seconds
 so the answer becomes 270 degrees 30 minutes and 0 seconds
which is written like: 270°30'0"
