Answer:310
Step-by-step explanation:
so use pemdas
Parenthesis,exponents multiplication, division , addition, and subtraction order
231*5-16+101)/4
first i'm assuming the parenthesis is over the whole thing
that the question should look like (231*5-16+101)/4
first parenthesis, 231*5=1,155
1,155-16=1,139+101= 1,240
1240/4= 310.
Hope this helps!
Answer:
∠ BDA = 55° , ∠ BCA = 70°
Step-by-step explanation:
∠ BOA = 360° - 250° = 110° ( angles round a point )
The central angle is twice the angle on the circle, subtended on the same arc
∠ BDA =
∠ BOA =
× 110° = 55°
OBCA is a tangent kite
Opposite angles sum to 180° , then
∠ BCA = 180° - ∠ BOA = 180° - 110° = 70°
