Answer:
Step-by-step explanation:
a. This is a right triangle with two sides and one angle given.
-We apply Sine Rule to find the angle B:
-The sides given are 10and 17 and the right angle 90°
Hence the angle B is 36.03°
b.We again use the sine rule to obtain the unknown angle w:
-15 corresponds to 90° and 9 corresponds to w°
Hence, the measure of w is 36.87°
The answer is probably -2
Answer:
The element is Boron(B)
Step-by-step explanation:
This is because on the periodic table, it shows that Boron has 5 protons and 5 electrons
D.) 15/6
- 3 times 52 = 156, and since you can't exactly convert it to a fraction then i'm assuming that it is 'D'.
- Ouma :>
Answer:
Step-by-step explanation:
- There are 4 of them (acute angles that is)
- Those 4 are less than 90 degrees.
- They have supplementary angles which are greater than 90 degrees.
- There are 4 of them also.
- The total number of angles should be 8 if there are 2 parallel lines and 1 transversal.
