Answer:
measure angle D = 62
Step-by-step explanation:
as the sum of measures of triangle =180
then (8x-40)+(4x-10)+(3x+20)=180
15x-30=180
x=(180+30)/15=14
XYZ SIMILAR TO PDQ
Y=D=3*14+20=62
ANSWER
The solution is 
EXPLANATION
We want to solve the simultaneous equations

and
.
We substitute equation (2) in to equation (1), to obtain

This has now become a linear equation in a single variable
.
We solve for x by grouping like terms.


We divide through by negative 3 to get;
.
Hence, the solution is 
The answer is d now do I get it lol
Answer:
Area of rectangles: l*b [LENGHT×BREADTH]
Therefore,
3/4 × 2/3 = Area
We do it as, 3*2/4*3
⇒ 6/12 = area
After simplification, we will get
1/2 = area of rectangular picture
