Answer:

(angles in a triangle add to 180 degrees)

(180 - 90) / 2 = 45

Use the sine rule to calculate the length a

(6 / sin(90)) x sin(45) = a

a = 4.242640687

<u>a = 4.2 mm (This answer is to 1 decimal place)</u>

➷ As the two lengths are a, this means it is an isosceles triangle.

The two unknown angles would be equal so we can calculate them:

(angles in a triangle equal 180 degrees)

(180 - 90) / 2 = 45

Now we can use the sine rule to calculate the length a

(6 / sin(90)) x sin(45) = a

a = 4.242640687

To one decimal place, your answer would be:

a = 4.2mm

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

Answer ASAP please, Will give brainliest.
nikdorinn [45]

Answer:

see below

Step-by-step explanation:

The measure of a minor arc is the same as the angle that forms it.

1. Since ∠GBJ = 90°, the answer is 90°.

2. ∠HBI = 180° - 151° = 29° so the answer is 29°.

3. ∠HBJ = 180° so the answer is 180°.

4. The reflex angle ∠GBI = 90 + 151 = 241° so the answer is 241°/

5. Since ∠GBJ = 90°, the reflex angle ∠GBJ = 360 - 90 = 270° so the answer is 270°.

6. ∠GBH = 180 - 90 = 90° so the reflex angle ∠GBH = 360 - 90 = 270° so the answer is 270°.
