Answer:
x=24
Step-by-step explanation:
Since line A and B are parallel, 3x+7 is equivalent to Angle 6 as they are corresponding angles.
We also know that 4x+5+Angle 6 = 180 as they are a linear pair. We can use substitution and substitute 3x+7 for Angle 6...
4x+5+3x+7=180
7x+12=180
7x=168
x=24
Only one angle can be right angle in obtuse angle
because if there are two right angles are in an obtuse angle it would be180 that doesn't make sence
Answer:
The answer is D.
Step-by-step explanation:
In order to find BC, you have to use Cosine Rule, cosθ = adjacent/hypotenuse. So you have to substitute the values into the formula :
Let adj. = BC,
Let hypo =30cm,
Let θ = 30°,
