<em>Since we are given with the three sides of the triangle and asked to determine the angle, we can use the cosine law.</em>
<em> b² = a² + c² - 2ac(cosB)</em>
<em>Substituting the known values,</em>
<em> (1.8)² = (2.4)² + (1.6)² - 2(2.4)(1.6)(cosB)</em>
<em>The value of B from the equation is 48.6°. </em>
Ok, make sure you put the powers correctly. I know what you mean but someone else may not. So it's step 2. This is because the 4 doesn't mean add a digit.
Looking at the angles of the triangles
N=S
M=R
O=T
so MON would be RTS
Step-by-step explanation:
4(2a + 5) that's the answer
Answer:
The answer is D
Step-by-step explanation:
- Let's see all choices in detail
A . 0 it is correct because 0 is an integer
B .It seems like rational number but it is not simplified yet so -18 \ 2= -9
C .
D . 4\5 it is decimal so it is rational number not integer
