Nesterboy [21]

Answer:

(3x - 2)(x - 5)

Step-by-step explanation:

3x² - 17a + 10

(3x - 2)(x - 5)

HELP ME PLEASE IVE BEEN STRUGGLING WITH THIS FOR SO LONG
Ber [7]

Answer:

<h2>m∠ACE = 90°</h2>

Step-by-step explanation:

Figure Interpretation:

m∠CBA + m∠CDE = 180

m∠BCA = (180-m∠CBA)/2

m∠DCE = (180-m∠CDE)/2

=======================

Then

m∠BCA + m∠DCE = (180-m∠CBA)/2 + (180-m∠CDE)/2

                                = [360-(m∠CBA+m∠CDE)]/2

                                = [360 - 180]/2

                                = 90

finally,

m∠ACE= 180 - (m∠BCA + m∠DCE)

             = 180 - 90

             = 90

The formula for the area of the triangle is A = 1/2bh.
nordsb [41]
The base would be 22 m squared since it is 22 x 10 = 220 and then you divide it by 2 to get 110 m squared.
