Answer:
<em>m∠1 = 90°</em>
<em>m∠2 = 35°</em>
<em>m∠3 = 55°</em>
Step-by-step explanation:
Find the diagram attached
From the diagram:
Given that <4 = 35°
The sum of the angle on a straight line at point A is 180°. Hence:
The sum of angle in the triangle ABC is 180°, hence;
The overall temperature would be 3.6°F as this is how much it was changed by
Answer=3.6°F
Answer:
2.8
Step-by-step explanation:
Options A,B and D. The correction about the area of the triangle are
- The apothem can be found using the Pythagorean theorem.
- The apothem can be found using the tangent ratio.
- The length of the apothem is approximately 2.5 cm.
<h3>How to solve for the length of the Apothem using the Pythagoras theorem</h3>
Firstly this is an equilateral triangle
3 of the sides have the length of 8.7cm
b = half of 8.7
= 4.35cm
To get A we have
a² + b² = c²
a² + 4.35² = 5²
When we solve this out we would have
a² = 25 - 18.9225
a ≈ 2.5 cm.
Hence we have proved that the first option is correct.
<u>For B,</u>
In an equilateral triangles, each of the angles = 60 degrees
60/2 = 30 is the angle that is made from the base
<h3>using tangent ratios </h3>
a / 4.35 = tan 30
then a = 4.35 tan 30
This would also give us an approximate of 2.5
For D
The calculations we have done based on the statements in A and B shows that D is correct as 2.5.
