Answer:
The measurement of the third exterior angle is 105°.
Step-by-step explanation:
The sum of the measures of the exterior angles of a polygon is always 360° ( However it is triangle or rectangle or etc..)
Since, a triangle has three exterior angles,
Given,
The measurement of two exterior angles of a triangle is 255°,
Let x be the third exterior angle,
Then by the above statement,
x + 255° = 360°
x = 360° - 255° = 105°
Hence, the measurement of the third exterior angle is 105°.
2x = 2√17 and 3x = 3√17
Step-by-step explanation:
- Step 1: Given length of the rectangle is 3x and breadth is 2x. Area is 102 m². Area of the rectangle = length × breadth
102 = 2x × 3x = 6x²
x² = 102/6 = 17
x = √17
Length 2x = 2√17 and Breadth = 3x = 3√17

So, the right option is 1. so if my ans was helpful u can follow me.
Answer:
Both of these examples are wrong. You cannot add/subtract integers and square roots together, however, you could add square roots together if they have the same number under the square root. For example, 2 - 2√6 will stay as 2 - 2√6 because they aren't like terms. 25 + 5√5 + 5√5 + 5 = 30 + 10√5 because 25 + 5 = 30 and 5√5 + 5√5 = 10√5. We can add 5√5 and 5√5 together because they have the same number under the square root. If we were to compute √2 + √3, we would just leave it as is because they don't have the same number under the square root.
