Subtract.
596 3/5 - (-81.8) [81.8 is below sea level so it is negative]
566.6 + 81.8 [Convert to decimal and distribute negative]
= 678.4 feet
Answer:s=6
Step-by-step explanation:
3 ( s + 4) = 30
3s+12=30
3s=18
s=6
Because these triangles are congruent, then angle a is the same degree measure as angle x; angle b is the same as y; and angle c is the same as z. We also know that, because of the Triangle Angle-sum Theorem, all the angles of a triangle have to add up to equal 180 degrees. So for us that means that a+b+c(which is also z) = 180. 50 + 2x + 40 + 4x + 8 = 180. Combining like terms we have 6x + 98 = 180. Subbtracting 98 from both sides gives us 6x = 82 and x = 13 2/3
Answer:
The answer in the attached figure
Step-by-step explanation:
step 1
Find the area of one blue square
step 2
Find the area of one orange triangle
Part 1) 
Divide the total area by the area of one orange triangle
Part 2) 
Divide the total area by the area of one blue square
Part 3) 
Let
x----> the number of blue squares
y ------> the number of orange triangles
we know that
Construct a table and prove different values for x and for y
we have
x=2, y=3
Two blue squares and three orange triangles
Area of blue squares
Area of an orange triangles
so
the area total is
11) 58 degrees for both angles
12) 72 and 108 degrees (left to right)
14) b=-3/2
I don’t have the rest I’m sorry
