Answer:

Step-by-step explanation:
Since this is a 30-60-90 triangle, we know that the sides have the following characteristic:
The side opposite to 30 degree angle: n
The side opposite to 60 degree angle: 
The side opposite to 90 degree angle: 2n
Since we know that 7 is opposite to 30-degree, and x is opposite to 60 degree, than we know that x = 
Answer:
15
Step-by-step explanation:
The calculator is actually correct because he entered division before addition.
Following the Bodmas rule of
B= Brackets O= Off D= Division M= Multiplication A= Addition S= Substraction
And from the question 56÷6 + 3 x 2, when bodmas is applied here it becomes ; (56÷6) +( 3 x2)
And when brackets is removed , it becomes
9+6 = 15.
Answer:
Malcom's average speed was 16 miles/hour.
Step-by-step explanation:
Given:
Distance from moon ridge to me tone = 32 miles.
Now including returned back journey.
So we can say that.
Total distance traveled = 
Also Given:
Time taken to travel total distance = 4 hours.
We need to find the average speed in miles per hour.
Solution:
Now we know that;
average speed is equal to Total distance traveled divided by Total time taken to travel the total distance.
framing in equation form we get;
average speed = 
Hence Malcom's average speed was 16 miles/hour.
A+b=-3, a=-3-b
ab=-35, and using a from above we get:
(-3-b)b=-35
-3b-b^2=-35
b^2+3b-35=0
b≈-7.6033 and 4.6033
So the two numbers are approximately -7.6033 and 4.6033
