Can you guys help me with these questions please

1. It is acute angled triangle. X° = 45°

2. 4 ways

3. Complementary(90°)

4. Supplementary (180°)

5. Acute angled triangle. X° = 45°

Step-by-step explanation:

1. Angles less than 90° is called acute angle. As all angles of the triangle are making an acute angle, thus it an acute angled triangle.

Angles made by a triangle are 180°.

Therefore, 70° + 65° + X° = 180°

Thus, 135° + x° = 180°

Thus, x° = 180° - 135°

Thus, x° = 45°

2. As to travel from one point on the pentagon to another (which are four in no. excluding the from one has started) there could be four ways.

3. 90° is known as complementary angle.

4. 180° is known as supplementary angle.

5. Similar to the first question, we can say it is an acute angled triangle. And we can find the x° as 45°.

50

Step-by-step explanation:

you add the 2 known angles then you subtrat that from 180

70+65=130

180-130=50
