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

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
