Answer:
u = 12
Step-by-step explanation:
formula : (base x height) / 2
60 x 2= 120
120 / 10 = 12
Answer:
HCF: 1
LCM: 84
Step-by-step explanation:
7 is a prime number. Nothing but 1 and 7 divide into which means that twelve and 7 have no highest common factor but 1.
The lowest common multiply (because 12 and 7 are prime to each other ) is 12 * 7 = 84
Answer:
120 degrees.
Step-by-step explanation:
This is a pentagon so the interior angles add up to 540 degrees, so we have:
4x + 4x + 4x + 3x + 3x = 540
18x = 540
x = 30 degrees.
So m < C = 4*30 = 120 degrees.
The true statement on Quadrilateral ABCD is B) A and C are supplementary. The theory is that when a quadrilateral is inscribed in a circle, the value of opposite angles always adds up to 180 degrees. The summation of two angles resulting to 180 degrees is called supplementary angles.
23pi/12 radians is equal to 345°
