Question

find the measure of each lettered angle.
a =
b =
c =
d =
e =

Explanation:

Step1: Calculate angle $a$

$a = 90^\circ - 70^\circ = 20^\circ$

Step2: Calculate angle $b$

$b = 90^\circ$

Step3: Calculate angle $c$

$c = 70^\circ$

Step4: Calculate angle $d$

$d = 180^\circ - 70^\circ = 110^\circ$

Step5: Calculate angle $e$

$e = 180^\circ$

Answer:

$a = 20^\circ$
$b = 90^\circ$
$c = 70^\circ$
$d = 110^\circ$
$e = 180^\circ$
