Answer:

thanks for a wonderful question the answer is you need to answer that because Hindi ka matutoto kung aasa ka sa ibaANSWERS:

For Number One.

\begin{gathered} \begin{array}{l} \tt m \angle C =180 - (20 + 100) \\ \tt m \angle C =180 - 120 \\ \tt m \angle C = 60 \degree \end{array}\end{gathered}

m∠C=180−(20+100)

m∠C=180−120

m∠C=60°

• Scalene Triangle

For Number Two.

\begin{gathered} \begin{array}{l} \tt m \angle B =180 - (55 + 35) \\ \tt m \angle B =180 - 90 \\ \tt m \angle B = 90 \degree \end{array}\end{gathered}

m∠B=180−(55+35)

m∠B=180−90

m∠B=90°

• Right Triangle

For Number Three.

\begin{gathered} \begin{array}{l} \tt m \angle A =180 - (68 + 44) \\ \tt m \angle A =180 - 112 \\ \tt m \angle A = 68 \degree \end{array}\end{gathered}

m∠A=180−(68+44)

m∠A=180−112

m∠A=68°

• Isosceles Triangle

For Number Four.

\begin{gathered} \begin{array}{l} \tt m \angle C=180 - (79 + 73) \\ \tt m \angle C =180 - 152\\ \tt m \angle C = 28\degree \end{array}\end{gathered}

m∠C=180−(79+73)

m∠C=180−152

m∠C=28°

• Scalene Triangle

For Number Five.

\begin{gathered} \begin{array}{l} \tt m \angle B =180 - (96 + 61) \\ \tt m \angle B =180 - 157 \\ \tt m \angle B = 23 \degree \end{array}\end{gathered}

m∠B=180−(96+61)

m∠B=180−157

m∠B=23°

• Scalene Triangle

For Number Six.

\begin{gathered} \begin{array}{l} \tt m \angle A =180 - (59 + 66) \\ \tt m \angle A =180 - 125\\ \tt m \angle A = 55 \degree \end{array}\end{gathered}

m∠A=180−(59+66)

m∠A=180−125

m∠A=55°

• Acute Triangle

For Number Seven.

\begin{gathered} \begin{array}{l} \tt m \angle C =180 - (1
