Answer:
123°
Step-by-step explanation:
2z +9 = x
y = z
2Z +9 + X + z +Y = 360
Substitute for Z
2Z +9 + 2z +9 + z + z = 360
6z +18 = 360
6Z = 342
Z = 57
2(57) +9 = 123
X = 123
Ratios are like fractions example 5:6= 5/6
so if you know the basics of fractions you can also use it as ratios.
Answer:
D. m<A = 61°, m<B = 57°, m<C = 61°
Step-by-step explanation:
The sum of all interior angles of a triangle is always equal to 180°.
Therefore, any set of given angle measurement of a triangle should sum up to 180°.
From the options given, the following angle measurements given in option D,
,m<A = 61°, m<B = 57°, m<C = 61° cannot be angle measurements of ∆ABC. This is because they sum up to give 179° instead of 180°.
The square root of 38 rounded up to 5 decimal places is 6.16441.
