Answer:
90 degrees because A is an acute angle so x equals 45 degrees and so I multiply that by 2
Step-by-step explanation:
The angles degrees are all less than 90 degrees. Therefore the triangle is an acute triangle
Answer:
t= -3.7
Step-by-step explanation:
1. 5( t+3)= -3.5
2. 5t+15= -3.5
3. 5t= -18.5
4. t= -3.7
-11 degrees. 6+5=11, and it went down, so negative 11 degrees
Answer:
1.25+√3 or 2.9821 to the nearest ten thousandth.
Step-by-step explanation:
sin 60 = √3/2, tan 45 = 1 and cos^2 60 = (1/2)^2 = 1/4
So we get 2 *√3/2 + 1 + 1/4
= √3 + 1.25
