Answer: draw a diagonal line
Step-by-step explanation:
like this:
since it's going up, it's a positive slope
By definition of supplementary angles,
∠ABD + ∠BDE = 180
5x + 17x - 18 = 180
22x = 198
x = 9
∠ABD = 5(9) = 45°
∠BDE = 180 - 45 = 135°
Answer:
43°
Step-by-step explanation:
7x+1+9x-7=90
16x-6=90
16x=96
x=6
the minor arc AD = 7x+1 =7(6)+1
= 42+1=43°
112 centimeters squared
Explanation:
The formula for area of a triangle is:
1/2 • base • height
REMEMBER, use the height that is perpendicular to the base. If not, your answer will be wrong
Use formula with given dimension of this triangle:
1/2 • 14 • 16 = 112
FINAL ANSWER WITH UNIT OF MEASURMENT:
112 centimeters squared
Have a nice day, hope this helps!
I hate math its so hard for no reason
