Help! What’s the measure of angle RST? Please explain, I want to learn.
KatRina [158]
The angle where the letter S is which would be angle RSQ = 1/2 x (131 +43) = 87

the angle opposite os RSQ would be PST and that would equal the same as RSQ which is 87

so 2 angles = 87 +87 = 174
 
so the other 2 angles need to equal 360 - 174 = 186

 since opposite angles equal each other divide that by 2 so 186 / 2 = 93

so both angle RST and PSQ are 93

The answer is D 93 degrees

(2x+3y+4z)(4x^2+9y^2+16z^2-6xy-12yz-8zx)
erma4kov [3.2K]
1.1 Factoring: 4x2+9y2+16z2-6xy-12yz-8xz

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: -6xy-12yz
Group 2: 16z2-8xz
Group 3: 4x2+9y2

Pull out from each group separately :

Group 1: (x+2z) • (-6y)
Group 2: (x-2z) • (-8z)
Group 3: (4x2+9y2) • (1)


Looking for common sub-expressions :

Group 1: (x+2z) • (-6y)
Group 3: (4x2+9y2) • (1)
Group 2: (x-2z) • (-8z)
