Answer:
CH = 22°
Step-by-step explanation:
We know that Arc AC and Arc CH both equal to 180°, therefore we can say;
AC + CH = 180°
158 + CH = 180°
CH = 180 - 158
CH = 22°
Hope this helps!
Answer:
Your answer would be 51.
Step-by-step explanation:
Remember the mathematical sequence: PEMDAS
P=parenthesis
E= exponents
M=multiply
D=divide
A=add
S=subtract.
In this case, there are no parenthesis and there are no exponents, so we multiply. Then there is no divide in this equation, so we go straight to add and subtract. Remember to do all this in the order of PEMDAS.
Answer:A
Step-by-step explanation:
Step 1: 3/10
Step 2: 6/15=2/5
Step 3: 3/10 x 2/5 = 3/25
Perimeter of a poligon= sum of all sides.
Perimeter of this triangle=s+(s+4)+3s=5s+4
An expression that represents the perimeter of this triangle is: 5s+4
