Answer:
56°
Step-by-step explanation:
The two marked angles are supplementary, so total 180°.
(2x +8) +(x -2) = 180
3x +6 = 180 . . . . . . . . . . collect terms
x + 2 = 60 . . . . . . . . . . . divide by 3
x = 58 . . . . . . . . . . . . . . subtract 2
∠DCB = x-2 = 58 -2
∠DCB = 56
Answer: 15 mL
Step-by-step explanation:
Before the stone the reading was 180 mL
When the stone was added the reading rose to 195 mL
So, we subtract them both, this will give us the volume of the stone
195 mL - 180 mL = 15 mL
Since it’s a square room, each side has length of 300ft. Simply use the Pythagorean Theorom to find the length from one corner to the opposing corner.
300^2 + 300^2 = c^2
90000 + 90000 = c^2
180000=c^2
Find the square root of 180000
C= 424.264069
The length from opposing corners is roughly 424.26ft
Answer:
"Can't be determined"
Step-by-step explanation:
From the triangles given in the picture,
Given:
m∠A = m∠C
m∠B = m∠D
But for the congruence of these triangles third condition is not given.
Therefore, congruence of these triangles can not be determined.
So the answer is "Can't be determined"
