Answer:
11 minutos.
Step-by-step explanation:
En las Olimpiadas de Matemáticas, la hora de inicio del evento se expresa en una ecuación simple: 2x + 6 = x + 17 ¿A qué hora comenzó el evento?
La hora en que comienza el evento en los juegos olímpicos se representa como x
Por tanto: 2x + 6 = x + 17
Recopilar términos similares
2x - x = 17 - 6
x = 11 minutos
Por lo tanto, los eventos comienzan en 11 minutos.
Answer:
1.5sin4x
Step-by-step explanation:
I just answered this question and got it right.
Important notes:
3 sides 1 angle - COSINE RULE
2 sides 2 angle - SINE RULE
since, the question wants to find the length of BC. In the end we will have 3 sides and 1 angle and use cosine rule
formula of cosine rule:
a² = b² + c² - 2bc Cos A° (to find the length)
Cos A° = b² + c² - a² / 2bc ( to find the angle, if there is given three sides and have to find the angle)
So just substitute,
a² = 13² + 15² - 2(13)(15) Cos 95°
a = 20.6 or 21
Answer: it's B
Step-by-step explanation:
you just have to use the AG and work backwards to find AD
