22 students in each class. (88 divided by 4=22)
True, this equation is a quadratic equation,.
Answer:
105.3
Step-by-step explanation:
cos(70)= 36/x
x=36/cos(70)
x=105.256958406
x~105.3
Answer:
Step-by-step explanation:
12x - 3 = 180 - (7x - 26) supplementary angles
19x = 209
x = 11
m∠DEC = 12(11) - 3 = 129°
m∠BCE = 7(11) - 26 = 51°
M∠ADE = 129 - 72 = 57° exterior angle rule
m∠EDB = 180 - 57 = 123° supplementary angles
m∠DBC = 57° corresponding angle to ADE
Ratio and Proportions
61:70=ratio of statue
?:22=61:70
?/22=61/70
Move 22 over the equal sign
?=61*22/70
?=1342/70
?=19.1714286
The tree is 19.1714286m tall
Hope this helps!
