The first shape is 60
The second shape is 15
That means it could be + - 3 degrees.
52 + 3 = 55
52 - 3 = 49
The temperature range is 49 to 55
Answer: The correct option is D.
Explanation:
It is given that the triangle ABC is an isosceles triangle. It is also given that the line BD is the median of triangle ABC.
Since DB is median it means point D divides the line AC in two equal parts.
The The median of an isosceles triangle is always a perpendicular bisector of the opposite side. Since the median is perpendicular on side AC, therefore the sides AB and CB are equal.
In triangle ABD and CBD,
.... (Isosceles triangle)
.... (D is midpoint of AC)
.... (Common Side)
Therefore option D is correct.
<h3><u>
Answer:</u></h3>
<h3><u>
Step-by-step explanation:</u></h3>
We know that:
- Total degrees of triangle: 180°
Using this clue, we can find m∠1.
- => 67 + 62 + m∠1 = 180
- => 129 + m∠1 = 180
- => m∠1 = 180 - 129
- => m∠1 = 51°
<h3><u>
Conclusion:</u></h3>
We have finally found the answer to the missing angle. The answer is 51°.
Hoped this helped.
