Answer:
C. 61
Step-by-step explanation:
add angles s and r together to find the sum of the line, 78+49= 119
then, subtract 180 with 119 which equals 61. you subtract 180 because thats the sum of the 3 degrees of a tirangle
The side length is 2/√3 times the apothem length, so is 10 cm. The area is that of 6 triangles, each with base 10 cm and height 5√3 cm.
.. 6*(1/2)*(10 cm)*(5√3 cm) = 150√3 cm^2
.. ≈ 259.8 cm^2
Answer:
Angle x = 72
Step-by-step explanation:
Angle AHI = Angle HIK = 63
(This is because the two angles are corresponding angles, HI//JK)
Angle x = 180 - 63 - 45
= 72
8,9 2,4 1,8 hope this may help!!
Let the numbers be X and X+1.
X+2(X+1)=29
X+2X+2=29
3X=29-2
X=27/3
X=9.
Thus, the Numbers are therefore 9 and 9+1=10
i.e 9 & 10.
Thus, when 9 is added to (2*10=20), the result is 29.
