Answer: It takes Him 1/4 hours to decorate both signs,
Step-by-step explanation:
Hi, since the area of a rectangle is equal to:
Area: length x width
Replacing with the values given;
Sign 1 =A1 = 2/3 x 1/4 =1/6 ft2
Sign 2 =A2= 1/2 x 1/3 = 1/6 ft2
If we sum both areas:
A1 +A2 = 1/6 + 1/6 = 2/6 ft2 = 1/3 ft2 (total area)
Since it takes Roberto 3/4 hour to decorate a 1-square-foot sign:
For 1/3 ft2
3/4 hour x 1/3 ft2 = 1/4 h
ITt takes Him 1/4 hours to decorate both signs,

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
Finish your statement... I'm anxious to help!
